see http://docs.python.org/lib/re-syntax.html I would try ^(?!.*\[G2\]) or if case is not significant ^(?!.*\[[Gg]2\]) but this is only a suggested starting point. It seems to me that it should work, but I don't know. >Is there a way to test regeps without setting up a separte test list? You could do a few interactive tests with Python or make a script.

In the second case, the null character at the start of the string is followed by (anything followed by [G2]) so the match fails and m.group is undefined. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
