Your problem description seems a little vague - which is
understandable, considering how embedded in your business model it is.
As for general recommendations, I'm no guru, but I would suggest
looking at the existing XML libraries in Haskell , and if that's
not powerful enough, check out parsec for building a custom parser.
I think to get more specific recommendations, you would need to give
more details about the problem. Hope this helps somewhat. Andrew
