NAME
    XML::Parser::Style::Tree - Tree style parser

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.
