That's a solution that works with the standard sgmllib from the Python
distribution. However this solution does not work with sgmllib from 
xml.parsers. I'm not sure if tag names with dots in their names are valid in XML 
or not. So this might explain the different behaviour however I don't think
that's the reason. Maybe I'll find the real reason over the weekend.
