.IX Title "Parser::Style::Tree 3"

\& 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, \f(CW\*(C`parse()\*(C'\fR 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 \*(L"0\*(R" 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
So for example the result of parsing:
\& <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo>
==================================================================
[foo, [{}, head, [{id => \*(L"a\*(R"}, 0, \*(L"Hello \*(R", em, [{}, 0, \*(L"there\*(R"]],
bar, [ {}, 0, \*(L"Howdy\*(R", ref, [{}]],
The root document \*(L"foo\*(R", has 3 children: a \*(L"head\*(R" element, a \*(L"bar\*(R"
element and the text \*(L"do\*(R". After the empty attribute hash, these are
represented in it's contents by 3 tag-content pairs.
