Parser:...le::Tree(3) User Contributed Perl Documentation Parser:...le::Tree(3) 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 ar- ray is a (possibly empty) hash reference containing attributes. The remain- der of the array is a sequence of tag-content pairs representing the con- tent of the element. So for example the result of parsing: Hello thereHowdydo 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. Entity Expansion The underlying Expat parser always expands predefined XML entity references ("<", ">", "&", """, "'") in both text content and at- tribute values before they reach the Tree style handlers. This is required by the XML specification and cannot be prevented. For example, "<" in the source XML will appear as "<" in the resulting tree structure. If you need access to the original unexpanded text, consider using the han- dler-based API with the "original_string" method on the Expat object in- stead of the Tree style. perl v5.44.0 2026-04-23 Parser:...le::Tree(3)
