interpreted = N
texte = Now that I think of it, you can also do a loop for all of the tags based on the number of levels of nested tags you expected. Thus, if you looped your existing code for a second repetition, it should catch the [b] in your example. Not an example of great coding but since this grep search=\[[bB]\]^(THE CLOSING TAG PATTERN THAT FOLLOWS*)\[/[bB]\] is unlikely to work, I thought I'd mention the option.

(WebDNA Talk) Subject: Re: WebDNA Grep help wanted I see why you require pairs, but that makes the grep much harder because, in the example you give, the search ends at the first [ when it should end at the first [/b. 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 Sent: Tue, 17 Feb 2004 21:44:26 +0100 To: (WebDNA Talk) Subject: WebDNA Grep help wanted Hi all, I have a messageboard developed in WebDNA.
