Swig does support things like that. Personally I use a 2-phase parsing  
setup. The first stage uses -xml then I parse the output and strip off the  
prefixes, generate a Renames.i file and then parse again with that  
renames.i file included. Gives me the proper names for everything.
The main downside is that this takes longer and my build system has a  
little problem with circular dependencies (this problem is related to the  
build tool really).
There is also the fance %rename stuff with regexps that was already  
discussed here.
All this won't do in this case, because of collision problems. As far as I  
know wxPython doesn't have those and that's why it works in their case.  
The OP's best bet is probably to use the xml processing part and take the  
namespace into account somehow. If everything fails he could maybe  
generate some C# code for the enums directly.
