NAME

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

SYNOPSIS

DESCRIPTION

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

When parsing a document, 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:

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.
