Peter is right. Now that I see what you're trying to do, I don't think it can be done in CF. I'm don't think it can be done in Java, either. To perform multiple actions within a single string (which you're doing since you're assuming multiple matches), you'll need to use REFind() and loop over each match.
<cfscript> s = yourString; start = 1; re = 'mailto:[EMAIL PROTECTED]'; while ( start lt len ( s ) ) { curMatch = REFindNoCase ( re, str, start, true ); if ( curMatch.pos[1] neq 0 ) { /** * call obfuscate() on each match * */ } start = curMatch.pos[1] + curMatch.len[1]; </cfscript> And, while I'm here, you're mailto string is missing a few valid characters in email addresses. Most commonly, the "-", but others are also valid - if rarely used. If you're interested in RFC-compliance then use [_A-Za-z0-9!##$%&'*+/=?^`{|}~-]+ instead of [\w.]+. Looks weird, I know, but the RFC says those characters are all legal in an email address and I've got customers who have "&" in their addresses. That's how I found out that the characters are legal (I'm not prone to perusing RFCs just for grins). :-) On 11/2/06, Ryan Mitchell <[EMAIL PROTECTED]> wrote: > ok, so i have a long string with emails within it, what i want to do is > identify the emails in teh string, and replace them with the result of the > function obfuscate(email)... > > so what im doing is this: > > function hideEmails(s) { > return rereplace(s,"(mailto:)([EMAIL > PROTECTED])",obfuscate("\1\2"),'ALL'); > } > > however, all this does is return an encrypted version of the string "\1\2", > instead of the backreferences. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| 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:258827 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
