Ended up looping over it shame though _____

Perl and maybe php support that kind of functionality, but in most languages it takes a work-around.

I think there was a thread on this a while back - if you search the list for rereplace and eval it should come up. The gist is that instead of running the function (mask in your case) directly in the rereplace, you replace the found string with an embedded function, so the replacement string would be something like "##mask('[EMAIL PROTECTED]')##" and the result would be something like "my name is steve and my email address is #mask('[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> ')# so if you want to email me go for it" Then you eval the result of the rereplace. There might be a DE in there somewhere too. I forget.

The email address could be anything so i want to be able to pass the back references from the regular expression into another function and be able to pass that back into the REReplace so i dont have to loop over the string looking for email addresses. Keep in mind that the string would be an entire HTML page.

Replace already takes the whole string. For that matter REReplace also takes the whole string and only replaces the match - you could use rereplace('[EMAIL PROTECTED]@als,'@','&123','ALL') and it would still return the entire string. And I'm pretty sure replacelist replaces every occurrance. You just have to watch out for recursive replacements.

For most symbols, just replace them with their &## counterpart: replacelist(str, "@,%", "&#asc('@')#,&#asc('%')#") If you need to replace &s you need to make sure to do so before any other symbols.
