Hi,

I am using coldfusionmx6 and created function.while it calling in xml it giving space.How to delete space?

<cffunction name="datereplaceformat" returntype="string">
  <cfargument default="" name="datechange" required="No">
   <cfargument default="" name="formatchange" required="No">
<CFSET var SDATE=reREPLACE(datechange,"#formatchange#"," ","all")>
<CFSET var rspace=reREPLACE(SDATE," ","","all")>
<cfreturn rspace>
</cffunction>

sample xml:

<cfoutput>

<va4>

<datepost>#trim(datereplaceformat(variables.NotPostedTransDate,"/"))#</datepost>

</va4>

</cfoutput>

In posting page it showing as

<va4>
