This module implements XML::Parser's Tree style parser.
.PP
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
of the element.
.PP
So for example the result of parsing:
.PP
.Vb 1
\& <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo>
.Ve
.PP
would be:
.PP
.Vb 7
\& Tag Content
\& ==================================================================
\& [foo, [{}, head, [{id => "a"}, 0, "Hello ", em, [{}, 0, "there"]],
\& bar, [ {}, 0, "Howdy", ref, [{}]],
\& 0, "do"
\& ]
\& ]
.Ve
.PP
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.
