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.
