NAME

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

CONTENTS

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.
