RE: regex help (Almost)
The regex works for most cases... but it's not stopping at the next ending tag... For example, the quote replac regex... I have [quote]heres a quote[/quote] Here's some text [quote]here's another quote[/quote] The expression replaces quote tags with blockquote tags unless it false between [code][/code] tags (which it doesntin this case) The result is blockquoteheres a quote[/quote] Heres some text [quote]here's another quote/blockquote Which of course should be blockquoteHeres a quote/blockquote Heres some text blockquotehere's another quote/blockquote This is the regex thats causing this... str = rereplace(str, (\[quote\](.*)\[/quote\])(?!((?!\[code\]).)*?\[/code\]), blockquote\2/blockquote, ALL); How can I change it to stop at the first [/quote] tag? -- No virus found in this outgoing message.

RE: regex help (Almost)
Are you using CFMX? If so you can specify minimal matching, which I think is probably the only way you can do this using a single regex.

RE: regex help (Almost)
Incase you havent realized regex's arent my forte! This seems to be the last little kink to get out of this thing and it will be set (or I'm going back to the original Jim Davis loop!) str = rereplace(str, (\[hr\])(?!(?!\[code\]).*?\[/code\]), hr, ALL); this regex works perfectly as long as the string doesn't contain [code][\code] blocks and doesn't have any single tags BEFORE the code (like [hr]) if there are code blocks then the above regex will only replace [hr] with hr AFTER the [code][/code] tags and leave any [hr]'s that come before it unchanged it doesn't replace the [hr]'s that fall inside the [code][/code] blocks either but that's what it's supposed to do, so apparently what it equates to is... replace [hr] if its after the last [/code] tag found and it should be... replace [hr] unless its after any [code] tag AND before the NEXT [/code] tag this block ... [hr] [code][b]some code[/b][/code] [hr] [code][b]some code[/b][/code] [hr] Is transformed into... [hr] pre[b]some code[/b]/pre [hr] pre[b]some code[/b]/pre hr The first 2 [hr] tags should be hr everything else works fine. just when I thought that I was actually getting better at regular expressions... sigh That is just the regex for tags without closing tags. The other regex for tags that have open and close works great like [b][/b] str = rereplace(str, (\[b\]([Aa-zZ0-9\s]*)\[/b\])(?!((?!\[code\]).)*?\[/code\]), b\2/b, ALL); cf-talk... Pimp my regex!

Re: regex help (Almost)
Still fighting that thing, eh? I spent 3 hours this afternoon trying to figure out why a simple INSERT query wouldn't work... finally I wrapped the query text in ## and a cfoutput, then copy/pasted it into Query Analyzer... only to find out that the problem was a new column in the database that was marked not nullable. I hadn't updated the insert to account for the new column. DANG, I hate when that happens. But, my my thought is this... Why not convert every single HR or BR tag to hr, then run rereplace with a regex that finds [\[code\].hr.\[\/code\]] and converts hr back to [HR]. Granted, it may not be the utmost in elegance (which is never pleasing), but it would work. Just a thought... I'll keep thinking on it too. Hard as that whole thinking thing may be.

RE: regex help (Almost)
At least I'm not alone :) I had thought about something to that effect but... I wanted content between [code] and [/code] to stay exactly as the user typed it.

Geeze, I sure hope anyone who read this paragraph: Still fighting that thing, eh? I spent 3 hours this afternoon trying to figure out why a simple INSERT query wouldn't work... finally I wrapped the query text in ## and a cfoutput, then copy/pasted it into Query Analyzer... only to find out that the problem was a new column in the database that was marked not nullable. I hadn't updated the insert to account for the new column. Knew I was speaking in shorthand. It's embarrasing. I mean, I pulled it out of the cfquery tag, wrapped it in a cfoutput instead, and rendered the text as-was to the screen... so I had my query, verbatim, as the cfquery tag would be receiving it. Then I copy/pasted THAT into query analyzer, so I could get the actual SQL Server error that was screwing me up. I haven't always been really good about my error handling, because, I guess, I've always thought that if you make the system so it works well, you don't get errors. And, mostly, it's held true. But, times like today remind me that error handling isn't just for end users... it's more for us than anything, because if we do it right, it'll TELL us what's wrong most of the time.
