Hi

but for me it is displaying whole xml file. that is not any body expect from this sample
I'm pasting xml file I'm using FYI

<?xml version="1.0" ?>
 <vxml version="2.0">
   <form id="form-record">
       <field name = "name1" expr = "'kamal'"/>
       <field name = "name2" expr = "'kalra'"/>
 <var name = "name3" expr = "'hi'"/>
 <var name = "uri" expr = "'submit.asp'"/>
       <block> 
         Say yes or no to submit a request to Snoop Servlet
         <submit method = "post" expr="uri" namelist = "name1 name2 name3"/> 
       </block>   
   </form>
 </vxml>
