Hi, Can anyone tell me hoq to write a regular expression which matches anything _except_ a litteral string ? For instance, I want to match any line which does not begin with Nomatch. So in the following : Line1 xxxx Line2 yyyy Nomatch zzzz Line3 aaaa Line 4 bbbb I would match every line except the one containing "Nomatch zzzz" Many thanks, DavidThread Next
