Hello Hari,
Can you right-click on the payload and choose view source? If it is displaying as </filed> then it is the content of your XML. What you can do to transform it to <filed></filed> is to use Java/XSLT mapping. Even if in the view source the field is <filed></filed>, it could still display as </filed> in some browsers (e.g moni).
Hope this helps,
Mark
