Python, libxml2 and run lists

So this last week I've been working on the run list as a web application. The front end is not so difficult, although I was requested to make the server side in Python; not my first choice... particularly as CERN's web server is not set up to use python as flexibly as PHP. So I run it as a python script in cgi-bin. This in turn uses my CherryPy server to retrieve xml. Then the fun begins: I am using libxml2 which is really not well documented. I'm compiling some notes on my wiki which might be helpful... difficult to believe that in the whole world there might be only a handful of programmers who have tried this.
