XML::Parser::Style::Tree(3) Tree style parser


use XML::Parser;
my $p = XML::Parser->new(Style => 'Tree');
my $tree = $p->parsefile('foo.xml');


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.
