How to build string in xml format using Xquery or XSLT

Question

I wish to frame the string request in wso2esb for that I am using Xquery. I have tried with string function in xquery but I am getting errors my xquery is like this. I wish to send this xml format to my client

<kls:XInput>
    <kls:XData>
         <DATA>
 <REQUEST ID_VALUE="5" NAME_VALUE="khfgd" MESSAGE_VALUE="Who" USER_TYPE="Daimond" PHNO_VALUE="65879541212" ></REQUEST>
</DATA>
  </kls:XData>
 </kls:XInput>

For above xml request i have used below xquery to get the deisre xml request

<x xmlns="http://ws.apache.org/ns/synapse">
  declare namespace xs = "http://www.w3.org/2001/XMLSchema";
  declare namespace env="http://eai.googl.afr/Envelope";
  declare namespace kls="http://eai.klsdop.inso/klsservice";
  declare variable $Id as xs:string+ external;
  declare variable $Name as xs:string+ external;
  declare variable $Message as xs:string+ external;
  declare variable $PHNO as xs:string+ external;

  element{'kls:XInput'}{
  element{'kls:XData'}{string(
  <DATA>      
    <REQUEST ID_VALUE="{$Id}" NAME_VALUE="{$Name}" MESSAGE_VALUE="{$Message}" USER_TYPE="Daimond" PHNO_VALUE="{$PHNO}" ></REQUEST>
</DATA>)
  }
  }

above parameters I am passing in my code and those reaching as well but unable to build the xquery. But I am getting error in my server like this.Because every time values will change.

Is there any way to solve the this in XSLT means adding CDATA in XSLT or Xquery.

Thanks in advance.

When you define your XQUERY, I think that root element 'x' have no namespace. However, I can see above that you have associated it with namespace "http://ws.apache.org/ns/synapse" : remove it and try again
