Many thanks for all fast and helpful answers!
I use HP-UX ANSI C, which has functions called regcomp and regexec. I
know the easiest way to solve my problem is to do the complement in the
code (if (!regexec (....) , but the idea is that all our regular
expressions are defined in a database, and a code change has much more
impact than a database adaptation for the company I work for. So I was
hoping to easily invert a RE. But now I think I'll get a rather complex
RE, which I think the database field is too small for. ;-)
Thanks again, and if anyone has some other ideas, I'll really
appreciate this!
