Ok, well if that works, great :) do you understand what you're doing there? (zero-width negative look-ahead assertion) You're looking for '<' followed by zero or more non-'>' characters, followed by a sequence that isn't '.*?>'. You can remove the negative character class ( [^>]* ) if you want, that's a bit redundant if you're going to use the negative look-ahead. -dave -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
