Dear all,

Thanks for all comments and tips on my "Conditional regex" question.
Nevertheless I'm still a bit of a novice when it deals with regular  
expressions.
Although I can see the logic in many of your tips I'm still unable to  
put the
bits and pieced together into a functional  expression.

Would anyone of you be so kind to provide me with a more elaborate
answer/example?

Thanks,

Marc
