One work-around is to try: grep search=\[([unurl]%5B[/unurl])(iIbB)\]&replace=<\1\2> I'm not completely sure of the sytax without testing, but the general idea is to match either [b] or [/b] to replace with
or in the same expression so that each instance is treated and not a pair of tags. Another way might be to bypass the first [i but I don't know how to not match a pattern in grep, only single characters as you've done: grep search=\[[bB]\]([NOT THE CLOSING TAG PATTERN THAT FOLLOWS]*)\[/[bB]\] Bill -----Original Message----- From: Palle Bo Nielsen
