1INTRODUCTION
2
3This is a Opensim UGAI server compatible implementation.
4It is written in Perl, based on apache (CGI or mod_perl)
5Not all of the functions of UGAI server are implemented, but currently,
6it supports the whole user login process and most of the operations on
7inventory, asset.
8
9The main purpose of this implemetation is to improve UGAI server's
10* stability - That's what Apache was born to do
11* scability - You can use reliable technology such as load balancing,
12 clustering that have been used for years.
13
14IMPLEMENTATION
15
16"*.cgi" are the server programs, for example of user server:
17opensim -> http://127.0.0.1:8002
18here -> http://127.0.0.1/user.cgi
19
20"lib" includes library file (*.pm) used by cgis.
21"test" includes testcases. Instructions are included in "*.pl" files.
22
23INSTALLNATION & CONFIGURATION
24
25* additional perl packages (Fedora, Suse, CentOS rpms available)
26 DBI
27 DBD::mysql
28 Data::UUID
29
30* A sample apache configuration file is included in "conf"
31 http-vhost.conf
32 mod_perl-startup.pl
33
34* lib/OpenSim/Config.pm need to be configured to fit your environment.
35 Please follow the comment in that file.

9=head1 SYNOPSIS
10
11 use XML::Simple;
12
13 my $ref = XMLin([<xml file or string>] [, <options>]);
14
15 my $xml = XMLout($hashref [, <options>]);
16
17Or the object oriented way:
18
19 require XML::Simple;
20
21 my $xs = XML::Simple->new(options);
22
23 my $ref = $xs->XMLin([<xml file or string>] [, <options>]);
24
25 my $xml = $xs->XMLout($hashref [, <options>]);
26
27(or see L<"SAX SUPPORT"> for 'the SAX way').
28
29To catch common errors:
30
31 use XML::Simple qw(:strict);
32
33(see L<"STRICT MODE"> for more details).

1863
1864=head1 QUICK START
1865
1866Say you have a script called B<foo> and a file of configuration options
1867called B<foo.xml> containing this:
1868
1869 <config logdir="/var/log/foo/" debugfile="/tmp/foo.debug">
1870 <server name="sahara" osname="solaris" osversion="2.6">
1871 <address>10.0.0.101</address>
1872 <address>10.0.1.101</address>
1873 </server>
1874 <server name="gobi" osname="irix" osversion="6.5">
1875 <address>10.0.0.102</address>
1876 </server>
1877 <server name="kalahari" osname="linux" osversion="2.0.34">
1878 <address>10.0.0.103</address>
1879 <address>10.0.1.103</address>
1880 </server>
1881 </config>
1882
1883The following lines of code in B<foo>:
1884
1885 use XML::Simple;
1886
1887 my $config = XMLin();
1888
1889will 'slurp' the configuration options into the hashref $config (because no
1890arguments are passed to C<XMLin()> the name and location of the XML file will
1891be inferred from name and location of the script). You can dump out the
1892contents of the hashref using Data::Dumper:
1893
1894 use Data::Dumper;
1895
1896 print Dumper($config);
1897
1898which will produce something like this (formatting has been adjusted for
1899brevity):
1900
1901 {
1902 'logdir' => '/var/log/foo/',
1903 'debugfile' => '/tmp/foo.debug',
1904 'server' => {
1905 'sahara' => {
1906 'osversion' => '2.6',
1907 'osname' => 'solaris',
1908 'address' => [ '10.0.0.101', '10.0.1.101' ]
1909 },
1910 'gobi' => {
1911 'osversion' => '6.5',
1912 'osname' => 'irix',
1913 'address' => '10.0.0.102'
1914 },
1915 'kalahari' => {
1916 'osversion' => '2.0.34',
1917 'osname' => 'linux',
1918 'address' => [ '10.0.0.103', '10.0.1.103' ]
1919 }
1920 }
1921 }
1922
1923Your script could then access the name of the log directory like this:
1924
1925 print $config->{logdir};
1926
1927similarly, the second address on the server 'kalahari' could be referenced as:
1928
1929 print $config->{server}->{kalahari}->{address}->[1];
1930
1931What could be simpler? (Rhetorical).
1932
1933For simple requirements, that's really all there is to it. If you want to
1934store your XML in a different directory or file, or pass it in as a string or
1935even pass it in via some derivative of an IO::Handle, you'll need to check out
1936L<"OPTIONS">. If you want to turn off or tweak the array folding feature (that
1937neat little transformation that produced $config->{server}) you'll find options
1938for that as well.
1939
1940If you want to generate XML (for example to write a modified version of
1941$config back out as XML), check out C<XMLout()>.
1942
1943If your needs are not so simple, this may not be the module for you. In that
1944case, you might want to read L<"WHERE TO FROM HERE?">.
1945
1946=head1 DESCRIPTION
1947
1948The XML::Simple module provides a simple API layer on top of an underlying XML
1949parsing module (either XML::Parser or one of the SAX2 parser modules). Two
1950functions are exported: C<XMLin()> and C<XMLout()>. Note: you can explicity
1951request the lower case versions of the function names: C<xml_in()> and
1952C<xml_out()>.
1953
1954The simplest approach is to call these two functions directly, but an
1955optional object oriented interface (see L<"OPTIONAL OO INTERFACE"> below)
1956allows them to be called as methods of an B<XML::Simple> object. The object
1957interface can also be used at either end of a SAX pipeline.
1958
1959=head2 XMLin()
1960
1961Parses XML formatted data and returns a reference to a data structure which
1962contains the same information in a more readily accessible form. (Skip
1963down to L<"EXAMPLES"> below, for more sample code).
1964
1965C<XMLin()> accepts an optional XML specifier followed by zero or more 'name =>
1966value' option pairs. The XML specifier can be one of the following:
1967
1968=over 4
1969
1970=item A filename
1971
1972If the filename contains no directory components C<XMLin()> will look for the
1973file in each directory in the SearchPath (see L<"OPTIONS"> below) or in the
1974current directory if the SearchPath option is not defined. eg:
1975
1976 $ref = XMLin('/etc/params.xml');
1977
1978Note, the filename '-' can be used to parse from STDIN.
1979
1980=item undef
1981
1982If there is no XML specifier, C<XMLin()> will check the script directory and
1983each of the SearchPath directories for a file with the same name as the script
1984but with the extension '.xml'. Note: if you wish to specify options, you
1985must specify the value 'undef'. eg:
1986
1987 $ref = XMLin(undef, ForceArray => 1);
1988
1989=item A string of XML
1990
1991A string containing XML (recognised by the presence of '<' and '>' characters)
1992will be parsed directly. eg:
1993
1994 $ref = XMLin('<opt username="bob" password="flurp" />');
1995
1996=item An IO::Handle object
1997
1998An IO::Handle object will be read to EOF and its contents parsed. eg:
1999
2000 $fh = IO::File->new('/etc/params.xml');
2001 $ref = XMLin($fh);
2002
2003=back
2004
2005=head2 XMLout()
2006
2007Takes a data structure (generally a hashref) and returns an XML encoding of
2008that structure. If the resulting XML is parsed using C<XMLin()>, it should
2009return a data structure equivalent to the original (see caveats below).
2010
2011The C<XMLout()> function can also be used to output the XML as SAX events
2012see the C<Handler> option and L<"SAX SUPPORT"> for more details).
2013
2014When translating hashes to XML, hash keys which have a leading '-' will be
2015silently skipped. This is the approved method for marking elements of a
2016data structure which should be ignored by C<XMLout>. (Note: If these items
2017were not skipped the key names would be emitted as element or attribute names
2018with a leading '-' which would not be valid XML).
2019
2020=head2 Caveats
2021
2022Some care is required in creating data structures which will be passed to
2023C<XMLout()>. Hash keys from the data structure will be encoded as either XML
2024element names or attribute names. Therefore, you should use hash key names
2025which conform to the relatively strict XML naming rules:
2026
2027Names in XML must begin with a letter. The remaining characters may be
2028letters, digits, hyphens (-), underscores (_) or full stops (.). It is also
2029allowable to include one colon (:) in an element name but this should only be
2030used when working with namespaces (B<XML::Simple> can only usefully work with
2031namespaces when teamed with a SAX Parser).
2032
2033You can use other punctuation characters in hash values (just not in hash
2034keys) however B<XML::Simple> does not support dumping binary data.
2035
2036If you break these rules, the current implementation of C<XMLout()> will
2037simply emit non-compliant XML which will be rejected if you try to read it
2038back in. (A later version of B<XML::Simple> might take a more proactive
2039approach).
2040
2041Note also that although you can nest hashes and arrays to arbitrary levels,
2042circular data structures are not supported and will cause C<XMLout()> to die.
2043
2044If you wish to 'round-trip' arbitrary data structures from Perl to XML and back
2045to Perl, then you should probably disable array folding (using the KeyAttr
2046option) both with C<XMLout()> and with C<XMLin()>. If you still don't get the
2047expected results, you may prefer to use L<XML::Dumper> which is designed for
2048exactly that purpose.
2049
2050Refer to L<"WHERE TO FROM HERE?"> if C<XMLout()> is too simple for your needs.
2051
2052
2053=head1 OPTIONS
2054
2055B<XML::Simple> supports a number of options (in fact as each release of
2056B<XML::Simple> adds more options, the module's claim to the name 'Simple'
2057becomes increasingly tenuous). If you find yourself repeatedly having to
2058specify the same options, you might like to investigate L<"OPTIONAL OO
2059INTERFACE"> below.
2060
2061If you can't be bothered reading the documentation, refer to
2062L<"STRICT MODE"> to automatically catch common mistakes.
2063
2064Because there are so many options, it's hard for new users to know which ones
2065are important, so here are the two you really need to know about:
2066
2067=over 4
2068
2069=item *
2070
2071check out C<ForceArray> because you'll almost certainly want to turn it on
2072
2073=item *
2074
2075make sure you know what the C<KeyAttr> option does and what its default value is
2076because it may surprise you otherwise (note in particular that 'KeyAttr'
2077affects both C<XMLin> and C<XMLout>)
2078
2079=back
2080
2081The option name headings below have a trailing 'comment' - a hash followed by
2082two pieces of metadata:
2083
2084=over 4
2085
2086=item *
2087
2088Options are marked with 'I<in>' if they are recognised by C<XMLin()> and
2089'I<out>' if they are recognised by C<XMLout()>.
2090
2091=item *
2092
2093Each option is also flagged to indicate whether it is:
2094
2095 'important' - don't use the module until you understand this one
2096 'handy' - you can skip this on the first time through
2097 'advanced' - you can skip this on the second time through
2098 'SAX only' - don't worry about this unless you're using SAX (or
2099 alternatively if you need this, you also need SAX)
2100 'seldom used' - you'll probably never use this unless you were the
2101 person that requested the feature
2102
2103=back
2104
2105The options are listed alphabetically:
2106
2107Note: option names are no longer case sensitive so you can use the mixed case
2108versions shown here; all lower case as required by versions 2.03 and earlier;
2109or you can add underscores between the words (eg: key_attr).
2110
2111
2112=head2 AttrIndent => 1 I<# out - handy>
2113
2114When you are using C<XMLout()>, enable this option to have attributes printed
2115one-per-line with sensible indentation rather than all on one line.
2116
2117=head2 Cache => [ cache schemes ] I<# in - advanced>
2118
2119Because loading the B<XML::Parser> module and parsing an XML file can consume a
2120significant number of CPU cycles, it is often desirable to cache the output of
2121C<XMLin()> for later reuse.
2122
2123When parsing from a named file, B<XML::Simple> supports a number of caching
2124schemes. The 'Cache' option may be used to specify one or more schemes (using
2125an anonymous array). Each scheme will be tried in turn in the hope of finding
2126a cached pre-parsed representation of the XML file. If no cached copy is
2127found, the file will be parsed and the first cache scheme in the list will be
2128used to save a copy of the results. The following cache schemes have been
2129implemented:
2130
2131=over 4
2132
2133=item storable
2134
2135Utilises B<Storable.pm> to read/write a cache file with the same name as the
2136XML file but with the extension .stor
2137
2138=item memshare
2139
2140When a file is first parsed, a copy of the resulting data structure is retained
2141in memory in the B<XML::Simple> module's namespace. Subsequent calls to parse
2142the same file will return a reference to this structure. This cached version
2143will persist only for the life of the Perl interpreter (which in the case of
2144mod_perl for example, may be some significant time).
2145
2146Because each caller receives a reference to the same data structure, a change
2147made by one caller will be visible to all. For this reason, the reference
2148returned should be treated as read-only.
2149
2150=item memcopy
2151
2152This scheme works identically to 'memshare' (above) except that each caller
2153receives a reference to a new data structure which is a copy of the cached
2154version. Copying the data structure will add a little processing overhead,
2155therefore this scheme should only be used where the caller intends to modify
2156the data structure (or wishes to protect itself from others who might). This
2157scheme uses B<Storable.pm> to perform the copy.
2158
2159=back
2160
2161Warning! The memory-based caching schemes compare the timestamp on the file to
2162the time when it was last parsed. If the file is stored on an NFS filesystem
2163(or other network share) and the clock on the file server is not exactly
2164synchronised with the clock where your script is run, updates to the source XML
2165file may appear to be ignored.
2166
2167=head2 ContentKey => 'keyname' I<# in+out - seldom used>
2168
2169When text content is parsed to a hash value, this option let's you specify a
2170name for the hash key to override the default 'content'. So for example:
2171
2172 XMLin('<opt one="1">Text</opt>', ContentKey => 'text')
2173
2174will parse to:
2175
2176 { 'one' => 1, 'text' => 'Text' }
2177
2178instead of:
2179
2180 { 'one' => 1, 'content' => 'Text' }
2181
2182C<XMLout()> will also honour the value of this option when converting a hashref
2183to XML.
2184
2185You can also prefix your selected key name with a '-' character to have
2186C<XMLin()> try a little harder to eliminate unnecessary 'content' keys after
2187array folding. For example:
2188
2189 XMLin(
2190 '<opt><item name="one">First</item><item name="two">Second</item></opt>',
2191 KeyAttr => {item => 'name'},
2192 ForceArray => [ 'item' ],
2193 ContentKey => '-content'
2194 )
2195
2196will parse to:
2197
2198 {
2199 'item' => {
2200 'one' => 'First'
2201 'two' => 'Second'
2202 }
2203 }
2204
2205rather than this (without the '-'):
2206
2207 {
2208 'item' => {
2209 'one' => { 'content' => 'First' }
2210 'two' => { 'content' => 'Second' }
2211 }
2212 }
2213
2214=head2 DataHandler => code_ref I<# in - SAX only>
2215
2216When you use an B<XML::Simple> object as a SAX handler, it will return a
2217'simple tree' data structure in the same format as C<XMLin()> would return. If
2218this option is set (to a subroutine reference), then when the tree is built the
2219subroutine will be called and passed two arguments: a reference to the
2220B<XML::Simple> object and a reference to the data tree. The return value from
2221the subroutine will be returned to the SAX driver. (See L<"SAX SUPPORT"> for
2222more details).
2223
2224=head2 ForceArray => 1 I<# in - important>
2225
2226This option should be set to '1' to force nested elements to be represented
2227as arrays even when there is only one. Eg, with ForceArray enabled, this
2228XML:
2229
2230 <opt>
2231 <name>value</name>
2232 </opt>
2233
2234would parse to this:
2235
2236 {
2237 'name' => [
2238 'value'
2239 ]
2240 }
2241
2242instead of this (the default):
2243
2244 {
2245 'name' => 'value'
2246 }
2247
2248This option is especially useful if the data structure is likely to be written
2249back out as XML and the default behaviour of rolling single nested elements up
2250into attributes is not desirable.
2251
2252If you are using the array folding feature, you should almost certainly enable
2253this option. If you do not, single nested elements will not be parsed to
2254arrays and therefore will not be candidates for folding to a hash. (Given that
2255the default value of 'KeyAttr' enables array folding, the default value of this
2256option should probably also have been enabled too - sorry).
2257
2258=head2 ForceArray => [ names ] I<# in - important>
2259
2260This alternative (and preferred) form of the 'ForceArray' option allows you to
2261specify a list of element names which should always be forced into an array
2262representation, rather than the 'all or nothing' approach above.
2263
2264It is also possible (since version 2.05) to include compiled regular
2265expressions in the list - any element names which match the pattern will be
2266forced to arrays. If the list contains only a single regex, then it is not
2267necessary to enclose it in an arrayref. Eg:
2268
2269 ForceArray => qr/_list$/
2270
2271=head2 ForceContent => 1 I<# in - seldom used>
2272
2273When C<XMLin()> parses elements which have text content as well as attributes,
2274the text content must be represented as a hash value rather than a simple
2275scalar. This option allows you to force text content to always parse to
2276a hash value even when there are no attributes. So for example:
2277
2278 XMLin('<opt><x>text1</x><y a="2">text2</y></opt>', ForceContent => 1)
2279
2280will parse to:
2281
2282 {
2283 'x' => { 'content' => 'text1' },
2284 'y' => { 'a' => 2, 'content' => 'text2' }
2285 }
2286
2287instead of:
2288
2289 {
2290 'x' => 'text1',
2291 'y' => { 'a' => 2, 'content' => 'text2' }
2292 }
2293
2294=head2 GroupTags => { grouping tag => grouped tag } I<# in+out - handy>
2295
2296You can use this option to eliminate extra levels of indirection in your Perl
2297data structure. For example this XML:
2298
2299 <opt>
2300 <searchpath>
2301 <dir>/usr/bin</dir>
2302 <dir>/usr/local/bin</dir>
2303 <dir>/usr/X11/bin</dir>
2304 </searchpath>
2305 </opt>
2306
2307Would normally be read into a structure like this:
2308
2309 {
2310 searchpath => {
2311 dir => [ '/usr/bin', '/usr/local/bin', '/usr/X11/bin' ]
2312 }
2313 }
2314
2315But when read in with the appropriate value for 'GroupTags':
2316
2317 my $opt = XMLin($xml, GroupTags => { searchpath => 'dir' });
2318
2319It will return this simpler structure:
2320
2321 {
2322 searchpath => [ '/usr/bin', '/usr/local/bin', '/usr/X11/bin' ]
2323 }
2324
2325The grouping element (C<< <searchpath> >> in the example) must not contain any
2326attributes or elements other than the grouped element.
2327
2328You can specify multiple 'grouping element' to 'grouped element' mappings in
2329the same hashref. If this option is combined with C<KeyAttr>, the array
2330folding will occur first and then the grouped element names will be eliminated.
2331
2332C<XMLout> will also use the grouptag mappings to re-introduce the tags around
2333the grouped elements. Beware though that this will occur in all places that
2334the 'grouping tag' name occurs - you probably don't want to use the same name
2335for elements as well as attributes.
2336
2337=head2 Handler => object_ref I<# out - SAX only>
2338
2339Use the 'Handler' option to have C<XMLout()> generate SAX events rather than
2340returning a string of XML. For more details see L<"SAX SUPPORT"> below.
2341
2342Note: the current implementation of this option generates a string of XML
2343and uses a SAX parser to translate it into SAX events. The normal encoding
2344rules apply here - your data must be UTF8 encoded unless you specify an
2345alternative encoding via the 'XMLDecl' option; and by the time the data reaches
2346the handler object, it will be in UTF8 form regardless of the encoding you
2347supply. A future implementation of this option may generate the events
2348directly.
2349
2350=head2 KeepRoot => 1 I<# in+out - handy>
2351
2352In its attempt to return a data structure free of superfluous detail and
2353unnecessary levels of indirection, C<XMLin()> normally discards the root
2354element name. Setting the 'KeepRoot' option to '1' will cause the root element
2355name to be retained. So after executing this code:
2356
2357 $config = XMLin('<config tempdir="/tmp" />', KeepRoot => 1)
2358
2359You'll be able to reference the tempdir as
2360C<$config-E<gt>{config}-E<gt>{tempdir}> instead of the default
2361C<$config-E<gt>{tempdir}>.
2362
2363Similarly, setting the 'KeepRoot' option to '1' will tell C<XMLout()> that the
2364data structure already contains a root element name and it is not necessary to
2365add another.
2366
2367=head2 KeyAttr => [ list ] I<# in+out - important>
2368
2369This option controls the 'array folding' feature which translates nested
2370elements from an array to a hash. It also controls the 'unfolding' of hashes
2371to arrays.
2372
2373For example, this XML:
2374
2375 <opt>
2376 <user login="grep" fullname="Gary R Epstein" />
2377 <user login="stty" fullname="Simon T Tyson" />
2378 </opt>
2379
2380would, by default, parse to this:
2381
2382 {
2383 'user' => [
2384 {
2385 'login' => 'grep',
2386 'fullname' => 'Gary R Epstein'
2387 },
2388 {
2389 'login' => 'stty',
2390 'fullname' => 'Simon T Tyson'
2391 }
2392 ]
2393 }
2394
2395If the option 'KeyAttr => "login"' were used to specify that the 'login'
2396attribute is a key, the same XML would parse to:
2397
2398 {
2399 'user' => {
2400 'stty' => {
2401 'fullname' => 'Simon T Tyson'
2402 },
2403 'grep' => {
2404 'fullname' => 'Gary R Epstein'
2405 }
2406 }
2407 }
2408
2409The key attribute names should be supplied in an arrayref if there is more
2410than one. C<XMLin()> will attempt to match attribute names in the order
2411supplied. C<XMLout()> will use the first attribute name supplied when
2412'unfolding' a hash into an array.
2413
2414Note 1: The default value for 'KeyAttr' is ['name', 'key', 'id']. If you do
2415not want folding on input or unfolding on output you must setting this option
2416to an empty list to disable the feature.
2417
2418Note 2: If you wish to use this option, you should also enable the
2419C<ForceArray> option. Without 'ForceArray', a single nested element will be
2420rolled up into a scalar rather than an array and therefore will not be folded
2421(since only arrays get folded).
2422
2423=head2 KeyAttr => { list } I<# in+out - important>
2424
2425This alternative (and preferred) method of specifiying the key attributes
2426allows more fine grained control over which elements are folded and on which
2427attributes. For example the option 'KeyAttr => { package => 'id' } will cause
2428any package elements to be folded on the 'id' attribute. No other elements
2429which have an 'id' attribute will be folded at all.
2430
2431Note: C<XMLin()> will generate a warning (or a fatal error in L<"STRICT MODE">)
2432if this syntax is used and an element which does not have the specified key
2433attribute is encountered (eg: a 'package' element without an 'id' attribute, to
2434use the example above). Warnings will only be generated if B<-w> is in force.
2435
2436Two further variations are made possible by prefixing a '+' or a '-' character
2437to the attribute name:
2438
2439The option 'KeyAttr => { user => "+login" }' will cause this XML:
2440
2441 <opt>
2442 <user login="grep" fullname="Gary R Epstein" />
2443 <user login="stty" fullname="Simon T Tyson" />
2444 </opt>
2445
2446to parse to this data structure:
2447
2448 {
2449 'user' => {
2450 'stty' => {
2451 'fullname' => 'Simon T Tyson',
2452 'login' => 'stty'
2453 },
2454 'grep' => {
2455 'fullname' => 'Gary R Epstein',
2456 'login' => 'grep'
2457 }
2458 }
2459 }
2460
2461The '+' indicates that the value of the key attribute should be copied rather
2462than moved to the folded hash key.
2463
2464A '-' prefix would produce this result:
2465
2466 {
2467 'user' => {
2468 'stty' => {
2469 'fullname' => 'Simon T Tyson',
2470 '-login' => 'stty'
2471 },
2472 'grep' => {
2473 'fullname' => 'Gary R Epstein',
2474 '-login' => 'grep'
2475 }
2476 }
2477 }
2478
2479As described earlier, C<XMLout> will ignore hash keys starting with a '-'.
2480
2481=head2 NoAttr => 1 I<# in+out - handy>
2482
2483When used with C<XMLout()>, the generated XML will contain no attributes.
2484All hash key/values will be represented as nested elements instead.
2485
2486When used with C<XMLin()>, any attributes in the XML will be ignored.
2487
2488=head2 NoEscape => 1 I<# out - seldom used>
2489
2490By default, C<XMLout()> will translate the characters 'E<lt>', 'E<gt>', '&' and
2491'"' to '&lt;', '&gt;', '&amp;' and '&quot' respectively. Use this option to
2492suppress escaping (presumably because you've already escaped the data in some
2493more sophisticated manner).
2494
2495=head2 NoIndent => 1 I<# out - seldom used>
2496
2497Set this option to 1 to disable C<XMLout()>'s default 'pretty printing' mode.
2498With this option enabled, the XML output will all be on one line (unless there
2499are newlines in the data) - this may be easier for downstream processing.
2500
2501=head2 NoSort => 1 I<# out - seldom used>
2502
2503Newer versions of XML::Simple sort elements and attributes alphabetically (*),
2504by default. Enable this option to suppress the sorting - possibly for
2505backwards compatibility.
2506
2507* Actually, sorting is alphabetical but 'key' attribute or element names (as in
2508'KeyAttr') sort first. Also, when a hash of hashes is 'unfolded', the elements
2509are sorted alphabetically by the value of the key field.
2510
2511=head2 NormaliseSpace => 0 | 1 | 2 I<# in - handy>
2512
2513This option controls how whitespace in text content is handled. Recognised
2514values for the option are:
2515
2516=over 4
2517
2518=item *
2519
25200 = (default) whitespace is passed through unaltered (except of course for the
2521normalisation of whitespace in attribute values which is mandated by the XML
2522recommendation)
2523
2524=item *
2525
25261 = whitespace is normalised in any value used as a hash key (normalising means
2527removing leading and trailing whitespace and collapsing sequences of whitespace
2528characters to a single space)
2529
2530=item *
2531
25322 = whitespace is normalised in all text content
2533
2534=back
2535
2536Note: you can spell this option with a 'z' if that is more natural for you.
2537
2538=head2 NSExpand => 1 I<# in+out handy - SAX only>
2539
2540This option controls namespace expansion - the translation of element and
2541attribute names of the form 'prefix:name' to '{uri}name'. For example the
2542element name 'xsl:template' might be expanded to:
2543'{http://www.w3.org/1999/XSL/Transform}template'.
2544
2545By default, C<XMLin()> will return element names and attribute names exactly as
2546they appear in the XML. Setting this option to 1 will cause all element and
2547attribute names to be expanded to include their namespace prefix.
2548
2549I<Note: You must be using a SAX parser for this option to work (ie: it does not
2550work with XML::Parser)>.
2551
2552This option also controls whether C<XMLout()> performs the reverse translation
2553from '{uri}name' back to 'prefix:name'. The default is no translation. If
2554your data contains expanded names, you should set this option to 1 otherwise
2555C<XMLout> will emit XML which is not well formed.
2556
2557I<Note: You must have the XML::NamespaceSupport module installed if you want
2558C<XMLout()> to translate URIs back to prefixes>.
2559
2560=head2 NumericEscape => 0 | 1 | 2 I<# out - handy>
2561
2562Use this option to have 'high' (non-ASCII) characters in your Perl data
2563structure converted to numeric entities (eg: &#8364;) in the XML output. Three
2564levels are possible:
2565
25660 - default: no numeric escaping (OK if you're writing out UTF8)
2567
25681 - only characters above 0xFF are escaped (ie: characters in the 0x80-FF range are not escaped), possibly useful with ISO8859-1 output
2569
25702 - all characters above 0x7F are escaped (good for plain ASCII output)
2571
2572=head2 OutputFile => <file specifier> I<# out - handy>
2573
2574The default behaviour of C<XMLout()> is to return the XML as a string. If you
2575wish to write the XML to a file, simply supply the filename using the
2576'OutputFile' option.
2577
2578This option also accepts an IO handle object - especially useful in Perl 5.8.0
2579and later for output using an encoding other than UTF-8, eg:
2580
2581 open my $fh, '>:encoding(iso-8859-1)', $path or die "open($path): $!";
2582 XMLout($ref, OutputFile => $fh);
2583
2584Note, XML::Simple does not require that the object you pass in to the
2585OutputFile option inherits from L<IO::Handle> - it simply assumes the object
2586supports a C<print> method.
2587
2588=head2 ParserOpts => [ XML::Parser Options ] I<# in - don't use this>
2589
2590I<Note: This option is now officially deprecated. If you find it useful, email
2591the author with an example of what you use it for. Do not use this option to
2592set the ProtocolEncoding, that's just plain wrong - fix the XML>.
2593
2594This option allows you to pass parameters to the constructor of the underlying
2595XML::Parser object (which of course assumes you're not using SAX).
2596
2597=head2 RootName => 'string' I<# out - handy>
2598
2599By default, when C<XMLout()> generates XML, the root element will be named
2600'opt'. This option allows you to specify an alternative name.
2601
2602Specifying either undef or the empty string for the RootName option will
2603produce XML with no root elements. In most cases the resulting XML fragment
2604will not be 'well formed' and therefore could not be read back in by C<XMLin()>.
2605Nevertheless, the option has been found to be useful in certain circumstances.
2606
2607=head2 SearchPath => [ list ] I<# in - handy>
2608
2609If you pass C<XMLin()> a filename, but the filename include no directory
2610component, you can use this option to specify which directories should be
2611searched to locate the file. You might use this option to search first in the
2612user's home directory, then in a global directory such as /etc.
2613
2614If a filename is provided to C<XMLin()> but SearchPath is not defined, the
2615file is assumed to be in the current directory.
2616
2617If the first parameter to C<XMLin()> is undefined, the default SearchPath
2618will contain only the directory in which the script itself is located.
2619Otherwise the default SearchPath will be empty.
2620
2621=head2 SuppressEmpty => 1 | '' | undef I<# in+out - handy>
2622
2623This option controls what C<XMLin()> should do with empty elements (no
2624attributes and no content). The default behaviour is to represent them as
2625empty hashes. Setting this option to a true value (eg: 1) will cause empty
2626elements to be skipped altogether. Setting the option to 'undef' or the empty
2627string will cause empty elements to be represented as the undefined value or
2628the empty string respectively. The latter two alternatives are a little
2629easier to test for in your code than a hash with no keys.
2630
2631The option also controls what C<XMLout()> does with undefined values. Setting
2632the option to undef causes undefined values to be output as empty elements
2633(rather than empty attributes), it also suppresses the generation of warnings
2634about undefined values. Setting the option to a true value (eg: 1) causes
2635undefined values to be skipped altogether on output.
2636
2637=head2 ValueAttr => [ names ] I<# in - handy>
2638
2639Use this option to deal elements which always have a single attribute and no
2640content. Eg:
2641
2642 <opt>
2643 <colour value="red" />
2644 <size value="XXL" />
2645 </opt>
2646
2647Setting C<< ValueAttr => [ 'value' ] >> will cause the above XML to parse to:
2648
2649 {
2650 colour => 'red',
2651 size => 'XXL'
2652 }
2653
2654instead of this (the default):
2655
2656 {
2657 colour => { value => 'red' },
2658 size => { value => 'XXL' }
2659 }
2660
2661Note: This form of the ValueAttr option is not compatible with C<XMLout()> -
2662since the attribute name is discarded at parse time, the original XML cannot be
2663reconstructed.
2664
2665=head2 ValueAttr => { element => attribute, ... } I<# in+out - handy>
2666
2667This (preferred) form of the ValueAttr option requires you to specify both
2668the element and the attribute names. This is not only safer, it also allows
2669the original XML to be reconstructed by C<XMLout()>.
2670
2671Note: You probably don't want to use this option and the NoAttr option at the
2672same time.
2673
2674=head2 Variables => { name => value } I<# in - handy>
2675
2676This option allows variables in the XML to be expanded when the file is read.
2677(there is no facility for putting the variable names back if you regenerate
2678XML using C<XMLout>).
2679
2680A 'variable' is any text of the form C<${name}> which occurs in an attribute
2681value or in the text content of an element. If 'name' matches a key in the
2682supplied hashref, C<${name}> will be replaced with the corresponding value from
2683the hashref. If no matching key is found, the variable will not be replaced.
2684Names must match the regex: C<[\w.]+> (ie: only 'word' characters and dots are
2685allowed).
2686
2687=head2 VarAttr => 'attr_name' I<# in - handy>
2688
2689In addition to the variables defined using C<Variables>, this option allows
2690variables to be defined in the XML. A variable definition consists of an
2691element with an attribute called 'attr_name' (the value of the C<VarAttr>
2692option). The value of the attribute will be used as the variable name and the
2693text content of the element will be used as the value. A variable defined in
2694this way will override a variable defined using the C<Variables> option. For
2695example:
2696
2697 XMLin( '<opt>
2698 <dir name="prefix">/usr/local/apache</dir>
2699 <dir name="exec_prefix">${prefix}</dir>
2700 <dir name="bindir">${exec_prefix}/bin</dir>
2701 </opt>',
2702 VarAttr => 'name', ContentKey => '-content'
2703 );
2704
2705produces the following data structure:
2706
2707 {
2708 dir => {
2709 prefix => '/usr/local/apache',
2710 exec_prefix => '/usr/local/apache',
2711 bindir => '/usr/local/apache/bin',
2712 }
2713 }
2714
2715=head2 XMLDecl => 1 or XMLDecl => 'string' I<# out - handy>
2716
2717If you want the output from C<XMLout()> to start with the optional XML
2718declaration, simply set the option to '1'. The default XML declaration is:
2719
2720 <?xml version='1.0' standalone='yes'?>
2721
2722If you want some other string (for example to declare an encoding value), set
2723the value of this option to the complete string you require.
2724
2725
2726=head1 OPTIONAL OO INTERFACE
2727
2728The procedural interface is both simple and convenient however there are a
2729couple of reasons why you might prefer to use the object oriented (OO)
2730interface:
2731
2732=over 4
2733
2734=item *
2735
2736to define a set of default values which should be used on all subsequent calls
2737to C<XMLin()> or C<XMLout()>
2738
2739=item *
2740
2741to override methods in B<XML::Simple> to provide customised behaviour
2742
2743=back
2744
2745The default values for the options described above are unlikely to suit
2746everyone. The OO interface allows you to effectively override B<XML::Simple>'s
2747defaults with your preferred values. It works like this:
2748
2749First create an XML::Simple parser object with your preferred defaults:
2750
2751 my $xs = XML::Simple->new(ForceArray => 1, KeepRoot => 1);
2752
2753then call C<XMLin()> or C<XMLout()> as a method of that object:
2754
2755 my $ref = $xs->XMLin($xml);
2756 my $xml = $xs->XMLout($ref);
2757
2758You can also specify options when you make the method calls and these values
2759will be merged with the values specified when the object was created. Values
2760specified in a method call take precedence.
2761
2762Note: when called as methods, the C<XMLin()> and C<XMLout()> routines may be
2763called as C<xml_in()> or C<xml_out()>. The method names are aliased so the
2764only difference is the aesthetics.
2765
2766=head2 Parsing Methods
2767
2768You can explicitly call one of the following methods rather than rely on the
2769C<xml_in()> method automatically determining whether the target to be parsed is
2770a string, a file or a filehandle:
2771
2772=over 4
2773
2774=item parse_string(text)
2775
2776Works exactly like the C<xml_in()> method but assumes the first argument is
2777a string of XML (or a reference to a scalar containing a string of XML).
2778
2779=item parse_file(filename)
2780
2781Works exactly like the C<xml_in()> method but assumes the first argument is
2782the name of a file containing XML.
2783
2784=item parse_fh(file_handle)
2785
2786Works exactly like the C<xml_in()> method but assumes the first argument is
2787a filehandle which can be read to get XML.
2788
2789=back
2790
2791=head2 Hook Methods
2792
2793You can make your own class which inherits from XML::Simple and overrides
2794certain behaviours. The following methods may provide useful 'hooks' upon
2795which to hang your modified behaviour. You may find other undocumented methods
2796by examining the source, but those may be subject to change in future releases.
2797
2798=over 4
2799
2800=item handle_options(direction, name => value ...)
2801
2802This method will be called when one of the parsing methods or the C<XMLout()>
2803method is called. The initial argument will be a string (either 'in' or 'out')
2804and the remaining arguments will be name value pairs.
2805
2806=item default_config_file()
2807
2808Calculates and returns the name of the file which should be parsed if no
2809filename is passed to C<XMLin()> (default: C<$0.xml>).
2810
2811=item build_simple_tree(filename, string)
2812
2813Called from C<XMLin()> or any of the parsing methods. Takes either a file name
2814as the first argument or C<undef> followed by a 'string' as the second
2815argument. Returns a simple tree data structure. You could override this
2816method to apply your own transformations before the data structure is returned
2817to the caller.
2818
2819=item new_hashref()
2820
2821When the 'simple tree' data structure is being built, this method will be
2822called to create any required anonymous hashrefs.
2823
2824=item sorted_keys(name, hashref)
2825
2826Called when C<XMLout()> is translating a hashref to XML. This routine returns
2827a list of hash keys in the order that the corresponding attributes/elements
2828should appear in the output.
2829
2830=item escape_value(string)
2831
2832Called from C<XMLout()>, takes a string and returns a copy of the string with
2833XML character escaping rules applied.
2834
2835=item numeric_escape(string)
2836
2837Called from C<escape_value()>, to handle non-ASCII characters (depending on the
2838value of the NumericEscape option).
2839
2840=item copy_hash(hashref, extra_key => value, ...)
2841
2842Called from C<XMLout()>, when 'unfolding' a hash of hashes into an array of
2843hashes. You might wish to override this method if you're using tied hashes and
2844don't want them to get untied.
2845
2846=back
2847
2848=head2 Cache Methods
2849
2850XML::Simple implements three caching schemes ('storable', 'memshare' and
2851'memcopy'). You can implement a custom caching scheme by implementing
2852two methods - one for reading from the cache and one for writing to it.
2853
2854For example, you might implement a new 'dbm' scheme that stores cached data
2855structures using the L<MLDBM> module. First, you would add a
2856C<cache_read_dbm()> method which accepted a filename for use as a lookup key
2857and returned a data structure on success, or undef on failure. Then, you would
2858implement a C<cache_read_dbm()> method which accepted a data structure and a
2859filename.
2860
2861You would use this caching scheme by specifying the option:
2862
2863 Cache => [ 'dbm' ]
2864
2865=head1 STRICT MODE
2866
2867If you import the B<XML::Simple> routines like this:
2868
2869 use XML::Simple qw(:strict);
2870
2871the following common mistakes will be detected and treated as fatal errors
2872
2873=over 4
2874
2875=item *
2876
2877Failing to explicitly set the C<KeyAttr> option - if you can't be bothered
2878reading about this option, turn it off with: KeyAttr => [ ]
2879
2880=item *
2881
2882Failing to explicitly set the C<ForceArray> option - if you can't be bothered
2883reading about this option, set it to the safest mode with: ForceArray => 1
2884
2885=item *
2886
2887Setting ForceArray to an array, but failing to list all the elements from the
2888KeyAttr hash.
2889
2890=item *
2891
2892Data error - KeyAttr is set to say { part => 'partnum' } but the XML contains
2893one or more E<lt>partE<gt> elements without a 'partnum' attribute (or nested
2894element). Note: if strict mode is not set but -w is, this condition triggers a
2895warning.
2896
2897=item *
2898
2899Data error - as above, but non-unique values are present in the key attribute
2900(eg: more than one E<lt>partE<gt> element with the same partnum). This will
2901also trigger a warning if strict mode is not enabled.
2902
2903=item *
2904
2905Data error - as above, but value of key attribute (eg: partnum) is not a
2906scalar string (due to nested elements etc). This will also trigger a warning
2907if strict mode is not enabled.
2908
2909=back
2910
2911=head1 SAX SUPPORT
2912
2913From version 1.08_01, B<XML::Simple> includes support for SAX (the Simple API
2914for XML) - specifically SAX2.
2915
2916In a typical SAX application, an XML parser (or SAX 'driver') module generates
2917SAX events (start of element, character data, end of element, etc) as it parses
2918an XML document and a 'handler' module processes the events to extract the
2919required data. This simple model allows for some interesting and powerful
2920possibilities:
2921
2922=over 4
2923
2924=item *
2925
2926Applications written to the SAX API can extract data from huge XML documents
2927without the memory overheads of a DOM or tree API.
2928
2929=item *
2930
2931The SAX API allows for plug and play interchange of parser modules without
2932having to change your code to fit a new module's API. A number of SAX parsers
2933are available with capabilities ranging from extreme portability to blazing
2934performance.
2935
2936=item *
2937
2938A SAX 'filter' module can implement both a handler interface for receiving
2939data and a generator interface for passing modified data on to a downstream
2940handler. Filters can be chained together in 'pipelines'.
2941
2942=item *
2943
2944One filter module might split a data stream to direct data to two or more
2945downstream handlers.
2946
2947=item *
2948
2949Generating SAX events is not the exclusive preserve of XML parsing modules.
2950For example, a module might extract data from a relational database using DBI
2951and pass it on to a SAX pipeline for filtering and formatting.
2952
2953=back
2954
2955B<XML::Simple> can operate at either end of a SAX pipeline. For example,
2956you can take a data structure in the form of a hashref and pass it into a
2957SAX pipeline using the 'Handler' option on C<XMLout()>:
2958
2959 use XML::Simple;
2960 use Some::SAX::Filter;
2961 use XML::SAX::Writer;
2962
2963 my $ref = {
2964 .... # your data here
2965 };
2966
2967 my $writer = XML::SAX::Writer->new();
2968 my $filter = Some::SAX::Filter->new(Handler => $writer);
2969 my $simple = XML::Simple->new(Handler => $filter);
2970 $simple->XMLout($ref);
2971
2972You can also put B<XML::Simple> at the opposite end of the pipeline to take
2973advantage of the simple 'tree' data structure once the relevant data has been
2974isolated through filtering:
2975
2976 use XML::SAX;
2977 use Some::SAX::Filter;
2978 use XML::Simple;
2979
2980 my $simple = XML::Simple->new(ForceArray => 1, KeyAttr => ['partnum']);
2981 my $filter = Some::SAX::Filter->new(Handler => $simple);
2982 my $parser = XML::SAX::ParserFactory->parser(Handler => $filter);
2983
2984 my $ref = $parser->parse_uri('some_huge_file.xml');
2985
2986 print $ref->{part}->{'555-1234'};
2987
2988You can build a filter by using an XML::Simple object as a handler and setting
2989its DataHandler option to point to a routine which takes the resulting tree,
2990modifies it and sends it off as SAX events to a downstream handler:
2991
2992 my $writer = XML::SAX::Writer->new();
2993 my $filter = XML::Simple->new(
2994 DataHandler => sub {
2995 my $simple = shift;
2996 my $data = shift;
2997
2998 # Modify $data here
2999
3000 $simple->XMLout($data, Handler => $writer);
3001 }
3002 );
3003 my $parser = XML::SAX::ParserFactory->parser(Handler => $filter);
3004
3005 $parser->parse_uri($filename);
3006
3007I<Note: In this last example, the 'Handler' option was specified in the call to
3008C<XMLout()> but it could also have been specified in the constructor>.
3009
3010=head1 ENVIRONMENT
3011
3012If you don't care which parser module B<XML::Simple> uses then skip this
3013section entirely (it looks more complicated than it really is).
3014
3015B<XML::Simple> will default to using a B<SAX> parser if one is available or
3016B<XML::Parser> if SAX is not available.
3017
3018You can dictate which parser module is used by setting either the environment
3019variable 'XML_SIMPLE_PREFERRED_PARSER' or the package variable
3020$XML::Simple::PREFERRED_PARSER to contain the module name. The following rules
3021are used:
3022
3023=over 4
3024
3025=item *
3026
3027The package variable takes precedence over the environment variable if both are defined. To force B<XML::Simple> to ignore the environment settings and use
3028its default rules, you can set the package variable to an empty string.
3029
3030=item *
3031
3032If the 'preferred parser' is set to the string 'XML::Parser', then
3033L<XML::Parser> will be used (or C<XMLin()> will die if L<XML::Parser> is not
3034installed).
3035
3036=item *
3037
3038If the 'preferred parser' is set to some other value, then it is assumed to be
3039the name of a SAX parser module and is passed to L<XML::SAX::ParserFactory.>
3040If L<XML::SAX> is not installed, or the requested parser module is not
3041installed, then C<XMLin()> will die.
3042
3043=item *
3044
3045If the 'preferred parser' is not defined at all (the normal default
3046state), an attempt will be made to load L<XML::SAX>. If L<XML::SAX> is
3047installed, then a parser module will be selected according to
3048L<XML::SAX::ParserFactory>'s normal rules (which typically means the last SAX
3049parser installed).
3050
3051=item *
3052
3053if the 'preferred parser' is not defined and B<XML::SAX> is not
3054installed, then B<XML::Parser> will be used. C<XMLin()> will die if
3055L<XML::Parser> is not installed.
3056
3057=back
3058
3059Note: The B<XML::SAX> distribution includes an XML parser written entirely in
3060Perl. It is very portable but it is not very fast. You should consider
3061installing L<XML::LibXML> or L<XML::SAX::Expat> if they are available for your
3062platform.
3063
3064=head1 ERROR HANDLING
3065
3066The XML standard is very clear on the issue of non-compliant documents. An
3067error in parsing any single element (for example a missing end tag) must cause
3068the whole document to be rejected. B<XML::Simple> will die with an appropriate
3069message if it encounters a parsing error.
3070
3071If dying is not appropriate for your application, you should arrange to call
3072C<XMLin()> in an eval block and look for errors in $@. eg:
3073
3074 my $config = eval { XMLin() };
3075 PopUpMessage($@) if($@);
3076
3077Note, there is a common misconception that use of B<eval> will significantly
3078slow down a script. While that may be true when the code being eval'd is in a
3079string, it is not true of code like the sample above.
3080
3081=head1 EXAMPLES
3082
3083When C<XMLin()> reads the following very simple piece of XML:
3084
3085 <opt username="testuser" password="frodo"></opt>
3086
3087it returns the following data structure:
3088
3089 {
3090 'username' => 'testuser',
3091 'password' => 'frodo'
3092 }
3093
3094The identical result could have been produced with this alternative XML:
3095
3096 <opt username="testuser" password="frodo" />
3097
3098Or this (although see 'ForceArray' option for variations):
3099
3100 <opt>
3101 <username>testuser</username>
3102 <password>frodo</password>
3103 </opt>
3104
3105Repeated nested elements are represented as anonymous arrays:
3106
3107 <opt>
3108 <person firstname="Joe" lastname="Smith">
3109 <email>joe@smith.com</email>
3110 <email>jsmith@yahoo.com</email>
3111 </person>
3112 <person firstname="Bob" lastname="Smith">
3113 <email>bob@smith.com</email>
3114 </person>
3115 </opt>
3116
3117 {
3118 'person' => [
3119 {
3120 'email' => [
3121 'joe@smith.com',
3122 'jsmith@yahoo.com'
3123 ],
3124 'firstname' => 'Joe',
3125 'lastname' => 'Smith'
3126 },
3127 {
3128 'email' => 'bob@smith.com',
3129 'firstname' => 'Bob',
3130 'lastname' => 'Smith'
3131 }
3132 ]
3133 }
3134
3135Nested elements with a recognised key attribute are transformed (folded) from
3136an array into a hash keyed on the value of that attribute (see the C<KeyAttr>
3137option):
3138
3139 <opt>
3140 <person key="jsmith" firstname="Joe" lastname="Smith" />
3141 <person key="tsmith" firstname="Tom" lastname="Smith" />
3142 <person key="jbloggs" firstname="Joe" lastname="Bloggs" />
3143 </opt>
3144
3145 {
3146 'person' => {
3147 'jbloggs' => {
3148 'firstname' => 'Joe',
3149 'lastname' => 'Bloggs'
3150 },
3151 'tsmith' => {
3152 'firstname' => 'Tom',
3153 'lastname' => 'Smith'
3154 },
3155 'jsmith' => {
3156 'firstname' => 'Joe',
3157 'lastname' => 'Smith'
3158 }
3159 }
3160 }
3161
3162
3163The <anon> tag can be used to form anonymous arrays:
3164
3165 <opt>
3166 <head><anon>Col 1</anon><anon>Col 2</anon><anon>Col 3</anon></head>
3167 <data><anon>R1C1</anon><anon>R1C2</anon><anon>R1C3</anon></data>
3168 <data><anon>R2C1</anon><anon>R2C2</anon><anon>R2C3</anon></data>
3169 <data><anon>R3C1</anon><anon>R3C2</anon><anon>R3C3</anon></data>
3170 </opt>
3171
3172 {
3173 'head' => [
3174 [ 'Col 1', 'Col 2', 'Col 3' ]
3175 ],
3176 'data' => [
3177 [ 'R1C1', 'R1C2', 'R1C3' ],
3178 [ 'R2C1', 'R2C2', 'R2C3' ],
3179 [ 'R3C1', 'R3C2', 'R3C3' ]
3180 ]
3181 }
3182
3183Anonymous arrays can be nested to arbirtrary levels and as a special case, if
3184the surrounding tags for an XML document contain only an anonymous array the
3185arrayref will be returned directly rather than the usual hashref:
3186
3187 <opt>
3188 <anon><anon>Col 1</anon><anon>Col 2</anon></anon>
3189 <anon><anon>R1C1</anon><anon>R1C2</anon></anon>
3190 <anon><anon>R2C1</anon><anon>R2C2</anon></anon>
3191 </opt>
3192
3193 [
3194 [ 'Col 1', 'Col 2' ],
3195 [ 'R1C1', 'R1C2' ],
3196 [ 'R2C1', 'R2C2' ]
3197 ]
3198
3199Elements which only contain text content will simply be represented as a
3200scalar. Where an element has both attributes and text content, the element
3201will be represented as a hashref with the text content in the 'content' key
3202(see the C<ContentKey> option):
3203
3204 <opt>
3205 <one>first</one>
3206 <two attr="value">second</two>
3207 </opt>
3208
3209 {
3210 'one' => 'first',
3211 'two' => { 'attr' => 'value', 'content' => 'second' }
3212 }
3213
3214Mixed content (elements which contain both text content and nested elements)
3215will be not be represented in a useful way - element order and significant
3216whitespace will be lost. If you need to work with mixed content, then
3217XML::Simple is not the right tool for your job - check out the next section.
3218
3219=head1 WHERE TO FROM HERE?
3220
3221B<XML::Simple> is able to present a simple API because it makes some
3222assumptions on your behalf. These include:
3223
3224=over 4
3225
3226=item *
3227
3228You're not interested in text content consisting only of whitespace
3229
3230=item *
3231
3232You don't mind that when things get slurped into a hash the order is lost
3233
3234=item *
3235
3236You don't want fine-grained control of the formatting of generated XML
3237
3238=item *
3239
3240You would never use a hash key that was not a legal XML element name
3241
3242=item *
3243
3244You don't need help converting between different encodings
3245
3246=back
3247
3248In a serious XML project, you'll probably outgrow these assumptions fairly
3249quickly. This section of the document used to offer some advice on chosing a
3250more powerful option. That advice has now grown into the 'Perl-XML FAQ'
3251document which you can find at: L<http://perl-xml.sourceforge.net/faq/>
3252
3253The advice in the FAQ boils down to a quick explanation of tree versus
3254event based parsers and then recommends:
3255
3256For event based parsing, use SAX (do not set out to write any new code for
3257XML::Parser's handler API - it is obselete).
3258
3259For tree-based parsing, you could choose between the 'Perlish' approach of
3260L<XML::Twig> and more standards based DOM implementations - preferably one with
3261XPath support.
3262
3263
3264=head1 SEE ALSO
3265
3266B<XML::Simple> requires either L<XML::Parser> or L<XML::SAX>.
3267
3268To generate documents with namespaces, L<XML::NamespaceSupport> is required.
3269
3270The optional caching functions require L<Storable>.

48=head1 DESCRIPTION
49
50XML::TreePP module parses XML file and expands it for a hash tree.
51And also generate XML file from a hash tree.
52This is a pure Perl implementation.
53You can also download XML from remote web server
54like XMLHttpRequest object at JavaScript language.
55
56=head1 EXAMPLES
57
58=head2 Parse XML file
59
60Sample XML source:
61
62 <?xml version="1.0" encoding="UTF-8"?>
63 <family name="Kawasaki">
64 <father>Yasuhisa</father>
65 <mother>Chizuko</mother>
66 <children>
67 <girl>Shiori</girl>
68 <boy>Yusuke</boy>
69 <boy>Kairi</boy>
70 </children>
71 </family>
72
73Sample program to read a xml file and dump it:
74
75 use XML::TreePP;
76 use Data::Dumper;
77 my $tpp = XML::TreePP->new();
78 my $tree = $tpp->parsefile( "family.xml" );
79 my $text = Dumper( $tree );
80 print $text;
81
82Result dumped:
83
84 $VAR1 = {
85 'family' => {
86 '-name' => 'Kawasaki',
87 'father' => 'Yasuhisa',
88 'mother' => 'Chizuko',
89 'children' => {
90 'girl' => 'Shiori'
91 'boy' => [
92 'Yusuke',
93 'Kairi'
94 ],
95 }
96 }
97 };
98
99Details:
100
101 print $tree->{family}->{father}; # the father's given name.
102
103The prefix '-' is added on every attribute's name.
104
105 print $tree->{family}->{"-name"}; # the family name of the family
106
107The array is used because the family has two boys.
108
109 print $tree->{family}->{children}->{boy}->[1]; # The second boy's name
110 print $tree->{family}->{children}->{girl}; # The girl's name
111
112=head2 Text node and attributes:
113
114If a element has both of a text node and attributes
115or both of a text node and other child nodes,
116value of a text node is moved to C<#text> like child nodes.
117
118 use XML::TreePP;
119 use Data::Dumper;
120 my $tpp = XML::TreePP->new();
121 my $source = '<span class="author">Kawasaki Yusuke</span>';
122 my $tree = $tpp->parse( $source );
123 my $text = Dumper( $tree );
124 print $text;
125
126The result dumped is following:
127
128 $VAR1 = {
129 'span' => {
130 '-class' => 'author',
131 '#text' => 'Kawasaki Yusuke'
132 }
133 };
134
135The special node name of C<#text> is used because this elements
136has attribute(s) in addition to the text node.
137See also L</text_node_key> option.
138
139=head1 METHODS
140
141=head2 new
142
143This constructor method returns a new XML::TreePP object with C<%options>.
144
145 $tpp = XML::TreePP->new( %options );
146
147=head2 set
148
149This method sets a option value for C<option_name>.
150If C<$option_value> is not defined, its option is deleted.
151
152 $tpp->set( option_name => $option_value );
153
154See OPTIONS section below for details.
155
156=head2 get
157

159
160 $tpp->get( 'option_name' );
161
162=head2 parse
163
164This method reads XML source and returns a hash tree converted.
165The first argument is a scalar or a reference to a scalar.
166
167 $tree = $tpp->parse( $source );
168
169=head2 parsefile
170

188
189 ( $tree, $xml, $code ) = $tpp->parsehttp( $method, $url, $body, $head );
190
191In array context, This method returns also raw XML source received
192and HTTP response's status code.
193
194=head2 write
195
196This method parses a hash tree and returns a XML source generated.
197
198 $source = $tpp->write( $tree, $encode );
199
200C<$tree> is a reference to a hash tree.
201
202=head2 writefile
203
204This method parses a hash tree and writes a XML source into a file.
205
206 $tpp->writefile( $file, $tree, $encode );
207
208C<$file> is a filename to create.
209C<$tree> is a reference to a hash tree.
210
211=head1 OPTIONS FOR PARSING XML
212
213This module accepts option parameters following:
214
215=head2 force_array
216
217This option allows you to specify a list of element names which
218should always be forced into an array representation.
219
220 $tpp->set( force_array => [ 'rdf:li', 'item', '-xmlns' ] );
221
222The default value is null, it means that context of the elements
223will determine to make array or to keep it scalar or hash.
224Note that the special wildcard name C<'*'> means all elements.
225
226=head2 force_hash
227
228This option allows you to specify a list of element names which
229should always be forced into an hash representation.
230
231 $tpp->set( force_hash => [ 'item', 'image' ] );
232
233The default value is null, it means that context of the elements
234will determine to make hash or to keep it scalar as a text node.
235See also L</text_node_key> option below.
236Note that the special wildcard name C<'*'> means all elements.
237
238=head2 cdata_scalar_ref
239
240This option allows you to convert a cdata section into a reference
241for scalar on parsing XML source.
242
243 $tpp->set( cdata_scalar_ref => 1 );
244
245The default value is false, it means that each cdata section is converted into a scalar.
246
247=head2 user_agent
248
249This option allows you to specify a HTTP_USER_AGENT string which
250is used by parsehttp() method.
251
252 $tpp->set( user_agent => 'Mozilla/4.0 (compatible; ...)' );
253
254The default string is C<'XML-TreePP/#.##'>, where C<'#.##'> is
255substituted with the version number of this library.
256
257=head2 http_lite
258
259This option forces pasrsehttp() method to use a L<HTTP::Lite> instance.
260
261 my $http = HTTP::Lite->new();
262 $tpp->set( http_lite => $http );
263
264=head2 lwp_useragent
265
266This option forces pasrsehttp() method to use a L<LWP::UserAgent> instance.
267
268 my $ua = LWP::UserAgent->new();
269 $ua->timeout( 60 );
270 $ua->env_proxy;
271 $tpp->set( lwp_useragent => $ua );
272
273You may use this with L<LWP::UserAgent::WithCache>.
274
275=head2 base_class
276
277This blesses class name for each element's hashref.
278Each class is named straight as a child class of it parent class.
279
280 $tpp->set( base_class => 'MyElement' );
281 my $xml = '<root><parent><child key="val">text</child></parent></root>';
282 my $tree = $tpp->parse( $xml );
283 print ref $tree->{root}->{parent}->{child}, "\n";
284
285A hash for <child> element above is blessed to C<MyElement::root::parent::child>
286class. You may use this with L<Class::Accessor>.
287
288=head2 elem_class
289
290This blesses class name for each element's hashref.
291Each class is named horizontally under the direct child of C<MyElement>.
292
293 $tpp->set( base_class => 'MyElement' );
294 my $xml = '<root><parent><child key="val">text</child></parent></root>';
295 my $tree = $tpp->parse( $xml );
296 print ref $tree->{root}->{parent}->{child}, "\n";
297
298A hash for <child> element above is blessed to C<MyElement::child> class.
299
300=head1 OPTIONS FOR WRITING XML
301
302=head2 first_out
303
304This option allows you to specify a list of element/attribute
305names which should always appears at first on output XML code.
306
307 $tpp->set( first_out => [ 'link', 'title', '-type' ] );
308
309The default value is null, it means alphabetical order is used.
310
311=head2 last_out
312
313This option allows you to specify a list of element/attribute
314names which should always appears at last on output XML code.
315
316 $tpp->set( last_out => [ 'items', 'item', 'entry' ] );
317
318=head2 indent
319
320This makes the output more human readable by indenting appropriately.
321
322 $tpp->set( indent => 2 );
323
324This doesn't strictly follow the XML Document Spec but does looks nice.
325
326=head2 xml_decl
327
328This module generates an XML declaration on writing an XML code per default.
329This option forces to change or leave it.
330
331 $tpp->set( xml_decl => '' );
332
333=head2 output_encoding
334
335This option allows you to specify a encoding of xml file generated
336by write/writefile methods.
337
338 $tpp->set( output_encoding => 'UTF-8' );
339
340On Perl 5.8.0 and later, you can select it from every
341encodings supported by Encode.pm. On Perl 5.6.x and before with
342Jcode.pm, you can use C<Shift_JIS>, C<EUC-JP>, C<ISO-2022-JP> and
343C<UTF-8>. The default value is C<UTF-8> which is recommended encoding.
344
345=head1 OPTIONS FOR BOTH
346
347=head2 utf8_flag
348
349This makes utf8 flag on for every element's value parsed
350and makes it on for an XML code generated as well.
351
352 $tpp->set( utf8_flag => 1 );
353
354Perl 5.8.1 or later is required to use this.
355
356=head2 attr_prefix
357
358This option allows you to specify a prefix character(s) which
359is inserted before each attribute names.
360
361 $tpp->set( attr_prefix => '@' );
362
363The default character is C<'-'>.
364Or set C<'@'> to access attribute values like E4X, ECMAScript for XML.
365Zero-length prefix C<''> is available as well, it means no prefix is added.
366
367=head2 text_node_key
368
369This option allows you to specify a hash key for text nodes.
370
371 $tpp->set( text_node_key => '#text' );
372
373The default key is C<#text>.
374
375=head2 ignore_error
376
377This module calls Carp::croak function on an error per default.
378This option makes all errors ignored and just return.
379
380 $tpp->set( ignore_error => 1 );
381
382=head2 use_ixhash
383
384This option keeps the order for each element appeared in XML.
385L<Tie::IxHash> module is required.
386
387 $tpp->set( use_ixhash => 1 );
388
389This makes parsing performance slow.
390(about 100% slower than default)
