    NAME

    XML::Parser::Style::Tree
     
    

    SYNOPSIS

      use XML::Parser;
      my $p = XML::Parser->new(Style => 'Tree');
      my $tree = $p->parsefile('foo.xml');
    
    
     

    DESCRIPTION

    This module implements XML::Parser's Tree style parser.

    When parsing a document, "parse()" will return a parse tree for the document. Each node in the tree takes the form of a tag, content pair. Text nodes are represented with a pseudo-tag of ``0'' and the string that is their content. For elements, the content is an array reference. The first item in the array is a (possibly empty) hash reference containing attributes. The remainder of the array is a sequence of tag-content pairs representing the content of the element.

    So for example the result of parsing:

      <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo>
    
    

    would be:
                 Tag   Content
      ==================================================================
      [foo, [{}, head, [{id => ``a''}, 0, ``Hello '',  em, [{}, 0, ``there'']],
                  bar, [         {}, 0, ``Howdy'',  ref, [{}]],
                    0, ``do''
            ]
      ]

    The root document ``foo'', has 3 children: a ``head'' element, a ``bar'' element and the text ``do''. After the empty attribute hash, these are represented in it's contents by 3 tag-content pairs.
