If you use libxml2 and libxslt (windows binaries) in python, you’ll know how annoying it is trying to figure out how to do something as the documentation is quite limited.
You can find out what is available in the python shell using dir() and __doc__ and help() but that’s a pain so I wrote a script to output a HTML file with the complete listing of the methods and prperties that libxml2 and libxslt have. Run it on your machine and you’ll have a ful list of all the methods (with __doc__ output) available with a permalink to each one and a link to google searching for references to that method.
Hope it helps
