Re: REReplace: Manipulating Backreferences

[Jamie Jackson]

That's not quite what I've got going on. Notice that while you used
backreferences, you didn't *process* them at all. (Maybe that's how I
should have phrased it: "Is it possible to *process* backreferences
within REReplace?")

Please remember that AFAIK, what I'm asking about is impossible, but I
was just making sure. Also, please note that I don't need help getting
this to work in another way (i.e. with a loop), as I have already made
a UDF that does it the "hard" way.

<cfsavecontent variable="myString">
[EMAIL PROTECTED] hello [EMAIL PROTECTED] goodbye
</cfsavecontent>
<cfscript>
// keep in mind that this is just illegal pseudocode
myString = rereplace(str,
          "([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-]+)+",
          emailAntiSpam(\1),
          "all");
</cfscript>
<cfoutput>
#myString#
</cfoutput>

############### DESIRED YIELD ###############
&#102;&#111;o&#64;&#98;a&#114;&#46;c&#111;&#109; hello
&#106;&#105;m&#64;&#106;a&#109;&#46;c&#111;&#109; goodbye

Thanks,
Jamie
