OpenSolaris 2009.06 - man page for xml::parser::style::tree (opensolaris section 3)

Parser::Style::Tree(3)	       User Contributed Perl Documentation	   Parser::Style::Tree(3)

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-con-
       tent pairs.
