Hi Les,
I have a little function for doing this:
<cffunction name="listCleanup" returntype="string" access="public"
hint="removes duplicates from given list and returns it alphanumerical sorted">
<cfargument name="lList" type="string" required="yes" hint="list to clear
up">
<cfargument name="bSort" type="Boolean" required="no" default="FALSE"
hint="whether to return sorted list or not">
<cfset var lReturn = "">
<cfset var strExistingKeys = structNew()>
<cfset var aReturnList = arrayNew(1)>
<cfloop list="#arguments.lList#" index="sElement">
<cfif NOT structKeyExists(strExistingKeys,sElement)>
<cfset arrayAppend(aReturnList,sElement)>
<cfset strExistingKeys[sElement] = TRUE>
</cfif>
</cfloop>
<cfif arguments.bSort>
<cfset arraySort(aReturnList,"textNoCase")>
</cfif>
<cfset lReturn = arrayToList(aReturnList)>
<CFRETURN lReturn>
</cffunction>
Greets,
Sigi
