anything that is surrounded by () is grouped and is returned as a back
reference
so
<cfset string = '<a class="classname" onclick="bla();"
href="bla.html">mylink</a>" />
<cfoutput>
#REReplaceNoCase(string,
"<a([^(href)]*)(href="")([^""]*)("")>([^<]*)</a>", "\3", "ALL")#
</cfoutput>
\1 = class="classname" onclick="bla();"
\2 = href="
\3 = bla.html
\4 = "
\5 = mylink
so because you are compounding everything together to get the whole a tag,
you can replace the a tag with a back referenced value.
so another example could be that you want to strip out all the attributes
other than the href. you could do that with..
REReplaceNoCase(string, "<a([^(href)]*)(href="")([^""]*)("")>([^<]*)</a>",
"<a href=""\3"">\5</a>", "ALL")
For reference i actually use the regular expressions cf docs
(http://livedocs.adobe.com/coldfusion/8/htmldocs/regexp_01.html)

Im trying to use it,
I even have Ben Forta Regular Expressions in 10 minutes.
I get the basic stuff, but the more complex stuff baffles me.
That last one Steve posted was a killer.

I always find it really funny how people try and avoid regex.
I * love * regex, and use it quite regularly, including doing all
sorts of crazy find and replaces in Eclipse to essentially do code
generation.
Regex FTW ;) RLY!
