Rob, Exactly, no real practical difference here. The only place it becomes more practical one way or the other is when the situation gets more complicated. For example, [] is used to group CHARACTERS... But ( | | ) can be used to group SUBSTRINGS ex. (ben is (cool|rad|awesome)) Such a grouping using [] would be a nightmare.

Ben took the shortcut of using a character set rather than explicitly stating the "OR" ( | ) condition. To be clear, though, either of these will remove any _, 1 or 2 from your value. So "foo1bar" will become "foobar". If the chars to be removed must be at the end of the string you want to use: <cfset strTest = REReplace( strTest, "_?[12]+$", "", "ALL" ) /> I varied Ben's regex slightly, but the gist is still there. The key difference is that the "$" forces the match to appear at the *end* of the string, not anywhere in the string. -- Rob Wilkerson On 9/27/06, Ray Champagne <[EMAIL PROTECTED]> wrote: > Ben, Claude, just so I know, what's the difference between your solutions? > Is it merely more than one way to skin a cat, or is one better than another? > > > <cfset strTest = REReplace( strTest, "[_12]+", "", "ALL" ) /> > > > > REreplace (MyString, "_|1|2", "", "all") > > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:254491 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
