                    vv => '',
                    v => [
                        'a',

            }
        }

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
