Results were pretty much the same for both HashSet and regex versions, but the latter is maybe nicer having the benefit of being native CF (if that's actually a benefit). HOWEVER! It took me a wee bit to work out why the regex one didn't quite work. Rather enigmatically, this will return: 137,141,227,290,296,33,394,481,526,535,58,644,72,861,908,913,925,960 When the answer should actually be: 137,14,141,227,290,296,33,394,481,526,535,58,6,644,72,861,908,913,925,960 Note that the 14 and the 6 have been "deduped" incorrectly. I scratched my head but it's because it's not matching the second grouping correctly: 14,141 is being matched as 14,14 After a bit of scratching around, I came up with this fix for it: REReplaceNoCase(ListSort(list,type),"([^,]+)((,\1)(\b))*","\1\4","ALL"); I tested this over quite a number of iterations and it seems to work OK. -- Adam --- You are currently subscribed to cfaussie as: [email protected] To unsubscribe send a blank email to [EMAIL PROTECTED] Aussie Macromedia Developers: http://lists.daemon.com.au/
