Reply To: GREP Bug in Lookaround?

I wasn’t clear in my answer. When I said “specific set of characters” I meant that positive lookahead has to look for characters that you specify. So, for example, you cannot use expressions such as a?c inside a positive lookahead because it’s not specific… it uses a wildcard.

So it works when you look for a specific character, but not with an expression such as “one or more characters”
