SPECIAL VARIABLES

$TEXT{ATTR} [ = '-' ]

Allow to set prefix for name of attribute nodes;

        <item attr="value" />
        # will be
        item => { -attr => 'value' };

        # with
        $TEXT{ATTR} = '+';
        # will be
        item => { '+attr' => 'value' };
        

$TEXT{NODE} [ = '#text' ]

Allow to set name for text nodes

        <item><sub attr="t"></sub>Text value</item>
        # will be
        item => { sub => { -attr => "t" }, #text => 'Text value' };

        # with
        $TEXT{NODE} = '';
        # will be
        item => { sub => { -attr => "t" }, '' => 'Text value' };

$TEXT{JOIN} [ = '' ]

Allow to set join separator for text node, splitted by subnodes

        <item>Test1<sub />Test2</item>
        # will be
        item => { sub => '', #text => 'Test1Test2' };

        # with
        $TEXT{JOIN} = '+';
        # will be
        item => { sub => '', #text => 'Test1+Test2' };

$TEXT{TRIM} [ = 1 ]

Trim leading and trailing whitespace from text nodes

        <item>  Test1  <sub />  Test2  </item>
        # will be
        item => { sub => '', #text => 'Test1Test2' };

        # with
        $TEXT{TRIM} = 0;
        # will be
        item => { sub => '', #text => '  Test1    Test2  ' };

%FORCE_ARRAY

Allow to force nodes to be represented always as arrays. If name is empty string, then ot means ALL

        <item><sub attr="t"></sub>Text value</item>

        # will be
        item => { sub => { -attr => "t" }, #text => 'Text value' };

        # with
        $FORCE_ARRAY{sub} = 1;
        # will be
        item => { sub => [ { -attr => "t" } ], #text => 'Text value' };

        # with
        $FORCE_ARRAY{''} = 1;
        # will be
        item => [ { sub => [ { -attr => "t" } ], #text => 'Text value' } ];

%FORCE_HASH

Allow to force text-only nodes to be represented always as hashes. If name is empty string, then ot means ALL

        <item><sub>Text value</sub><any>Text value</any></item>

        # will be
        item => { sub => 'Text value', any => 'Text value' };

        # with
        $FORCE_HASH{sub} = 1;
        # will be
        item => { sub => { #text => 'Text value' }, any => 'Text value' };

        # with
        $FORCE_HASH{''} = 1;
        # will be
        item => { sub => { #text => 'Text value' }, any => { #text => 'Text value' } };

@STRIP_KEY

Allow to strip something from tag names by regular expressions

        <a:item><b:sub>Text value</b:sub></a:item>

        # will be
        'a:item' => { 'b:sub' => 'Text value' };

        # with
        @STRIP_KEY = (qr/^[^:]+:/);
        # will be
        'item' => { 'sub' => 'Text value' };

SEE ALSO

• XML::Parser

  The parser itself

• XML::Parser::EasyTree

  Another EasyTree (I didn't found it before my first commit of this package because of missing '::Style' in it's name)

  But since XML::Parser::EasyTree and XML::Parser::Style::EasyTree use same style name, they're mutual exclusive ;(

  So, all the functionality was moved to ETree, and EasyTree was kept as a compatibility wrapper

• XML::Bare

  Very-very fast XML parser. Recommend to look

• XML::Hash::LX

  Similar behaviour, same output, but using XML::LibXML
