It does not. There was significant work done years ago to try and create an XML library, but there was limited success. You might search the UDF library and see if any of the work done would prove useful.

Personally - I've avoided using XML, favoring either the native INI files for configurations or JSON for data exchange. I wrote a JSON parsing function in Kix, but that's part of our commercial tool set and not available publicly.
