How to create custom iq

Hi,
I am creating a small university project, and need some help with it.
What I am doing is, I am sending an < iq /> stanza with xmlns "test:mytest" and in response I want to get the follwoing response.

<iq xmlns='jabber:client' id='df33f' type='result' from='user@server1' to='user@server2'>   <query xmlns='test:mytest' />      <myterms>         <item>            <name>testName</name>                       <properties>                  <property>                     <name>property name</name>                     <value>558</value>                  </property>                  <property>                     <name>property name 2</name>                     <value>560</value>                  </property>               </properites>         </item>      </myterms></iq>

I am using Smack-3.2.2,

Can anyone please help me, how can I set that response?
