Thanks for the reply
if the docs say that (?=...) will check for it but not include it in the
results, then
REFindNoCase("(?=(\[code\]))(.*?)(?=(\[\/code\]))",tmpContent,1,true);
should do exactly that.
Is this an issue with the reg exp engine in cf or the reg exp its self?
thats what I am wanting to get to the bottom of
Steve

You will find as you use regular expressions more that it is often easier to
replace the contents of a string than to use find and then extract it.
eg.
<cfset string = "bla bla bla [code] this is stuff [/code] bla bla bla [code]
this is more stuff [/code]">
<cfset tagName = "code">
<cfset regex = ".*?(\[" & tagName & "\])(.*?)(\[/" & tagName & "\])">
<cfset match = reFindNoCase(regex,string,1,true)>
<cfoutput>
<div style="font-family: courier;">
String: "#string#"<br />
Regex: "#regex#"<br />
</div>
</cfoutput>
<br />
<strong>Using reFindNoCase()</strong>
<br />
<cftry>
<cfoutput>
#mid(string,match.pos[2],match.len[2])#<br />
#mid(string,match.pos[3],match.len[3])#<br />
#mid(string,match.pos[4],match.len[4])#<br />
</cfoutput>
<cfcatch>
<cfoutput>Done!</cfoutput>
</cfcatch>
</cftry>
<cfset newString = reReplaceNoCase(string,regex,'\1<br />\2<br />\3<br
/>','all')>
<br />
<strong>Using reReplaceNoCase()</strong>
<br />
<cfoutput>#newString#</cfoutput>
