Split a message into multiple instances

Hi Experts

   I have a outbound interface that contains

      <get_UserDetails>

         <Items>

               <id>1</id>

               <name>Harish</name>

               <age>25</age>

         <Items>

         <Items>

               <id>2</id>

               <name>Manish</name>

               <age>30</age>

         <Items>

   </get_UserDetails>

  Here depending on the <Items> node I want to generate that many inbound interface instances.

  I do not want to use ccBPM. How can I achieve this?

Thanks
