There is plenty of excellent code on CPAN servers. If you don't know what to read visit https://metacpan.org/recent and pick at random :)
Also, reading David Golden's code was particulary insightful. It's not overly verbose, not necessarily self-documenting but it's almost always well commented, not always easy to understand but it looks efficient. If you're allergic to postfixed ifs and fors, then avoid reading it because it has a lot of those.

]]>Together with an XSD it makes it really easy to go from an XML string or file to a Perl data structure and vice-versa, which is what XML::Simple provides and I expect many users of that are looking for, rather than xpath queries for every node. It also has the advantage that it fixes most of the parsing problems inherent in the XML::Simple (especially with the default options), so potentially increasing the robustness of code by enforcing validation in the conversion process.
