Debatching before hitting the transform mapping

I’ve been through most of the walkthroughs and demos on debatching using xpath and envelope schema and they have worked perfectly. However, i’m unable to implement that functionality in our existing project.  Essentially, the project has a pretty simple orchestration that has a map transformation and is working properly in that the message comes into the IN folder and is processed correctly and placed into the OUT folder.  I simply want to make 1 change to an otherwise functional solution – our project must debatch a message into individual messages before they hit the mapping.

The incoming message has multiple items and each item must become a seperate file.

<root>

   <Item>

    <element1>

    <element2>

  </item>

   <Item>

    <element1>

    <element2>

  </item>

</root>

Any help would be very much appreciated.  Thank you gurus!
