Hi Andy, Last time I worked on the xupdate source code I used this download from sourceforge and it matched up in the debugger.
http://sourceforge.net/project/showfiles.php?group_id=75532&package_id=160698&release_id=348903 Start with the 0.3 version. I have used xupdate with Xindice extensively but I didn't have any namespace so I don't know off the top of my head how to fix this particular NPE. If you can spend some more time tracking this into the xupdate source code. Please keep us abreast of any results you find.
