Tricky Mapping Scenario : Leads pls

Hi folks i have a tricky mapping requirement.

I would appreciate your help. I think i need to go in for Java mapping but i am not very good at it. If required can someone guide me with doing it in DOM?

Thanks,

Hank

Source Structure

RequestBody->Summary(1-unbounded)

ManagerName(1)

ManagerID(1)

DistributerID(0-1)

Distributer(0-1)

Seller(0-1)

SellerID(0-1)

Here is how it goes:

-The summary has details about a manager.

-A manager may either have a Distributor directory under him - If he has a distributor under him , that distributor will always have a seller assigned to him.

- A manager can have a Seller directly assigned under him.

Pls look at this sample Source and Target XML desired
