In Regular Expressions, just like life, there are often about a bazillion ways to do something. For example, in CF6+, you can identify digits with [0-9], [1234567890], or [[:digit:]].
In a character class (anything in []) there are odd rules about what needs to be escaped when. For example, this: [[]] will correctly match square brackets. However, to add a backslash, you can't just escape the backslash: [\\[]] -- you now need to escape all the special chars: [\\\[\]] Weird, eh? Anyway, the answer is that in your example, you don't really need t escape the special characters, but it doesn't hurt anything. I'm sure tht didn't so muuch clarify things as explain why you're confused, but it's the best I could do on short notice. :-) --Ben Rick Faircloth wrote: > Hmmm..I'm getting conflicting info from the list... > > One said to escape the characters... \.\$, (don't > know why the comma wasn't escaped...perhaps > it isn't "special"...(now it's sad because it's not "special"... ;o) > > Another said they don't need to be escaped... > > You're coming down on the escape side... > > would it be REReplace(string, "[\.\$,]", "", "All") > or > would it be REReplace(string, "[\.\$\,]", "", "All") > > ? > > Just for the record, I implemented it without the > escapes yesterday and it seems to be performing correctly... > > Rick ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:234624 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
