This is similar to the Tree style, except that a hash object is created for each element. The corresponding object will be in the class whose name is created by appending "::" and the element name to the package set with the Pkg option. Non-markup text will be in the ::Characters class. The contents of the corresponding object will be in an anonymous array that is the value of the Kids property for that object. =head1 SEE ALSO L<XML::Parser::Style::Tree> =cut
