I'm actually glad that Tom submitted the solution he
did. I have to admit to never using the optional start and
returnsubstrings arguments to reFind. I ran his example:
<cfset string =
"?thisID=12&thatID=20&TheOtherID=30&numPageID=1000&TheThirdID=40">
<CFDump var="#string#"><br>
<cfset reResults = reFind("numPageID=([0-9]+)",string, 1,true)>
<CFDump var="#reResults#"><br>
<cfset theNum = mid(string, reResults.pos[2],reResults.len[2])>
<CFDump var="#theNum#"><br>
... and now I actually understand what it's doing. well worth the
effort.
This was fun. Let's do another! :)

The "most elegant" solution, to me (subjectively) was Tom's. It was
short, 2 lines, 2 CF functions, easy to read and figure out what was
going on. Dare I say pretty?
<cfset reResults = reFind("numPageID=([0-9]+)", CGI.HTTP_REFERER,
1,true)>
<cfset theNum = mid(CGI.HTTP_REFERER,
reResults.pos[2],reResults.len[2])>
Marlon wins for least amount of characters. Concise, efficient but
hard for me to follow the regex. Definitely a guy's solution. He
could have made it one character shorter by using "gettoken" instead
of "listgetat"!
<cfset pagenum =
listgetat(rereplacenocase(CGI.HTTP_REFERER,"[(?|&)]*numpageID=(\d*)","#chr(10)#\1#chr(10)#","all"),2,chr(10))>
Chris, Rick and Anthony's solutions were just about the same. Logical
and easy to understand.
<cfset ReferrerQS = ListLast(CGI.HTTP_REFERER, "?")>
<cfloop index="eachParamSet" list="#ReferrerQS#"
delimiters="&">
<cfif ListFirst(eachParamSet,"=") IS "numPageID">
<CFSet MyNumPageID = ListLast(eachParamSet,"=")>
</cfif>
</cfloop>
Mine was the worst, which is why I submitted this to the group to begin
with!
Thanks for playing!
