Yanic Inizan have implemented XPath on GXml in a few hours!!! Wow!!!
It was the first requested feature for GXml after a poll in G+. Now is available upstream.
For QA reasons, we need to add Unit Tests to this XPath implementation. I really love to see tests mimic different use cases but all of XPath 3.1 specification, this will help us to know where libxml2’s implementation is and how we can improve them using GXml.
Just to comment, if some feature or function is missing, we should add an expected fail case, in order to finish correctly make check, and to leave space to change it as how it should be when this feature is considered XPath 3.1 compliant.
