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.
