Mapping an XML from an input element to Target

Hi ,

I have an XML coming in source Element as below :

<?xml version="1.0" encoding="UTF-8"?>

<ResponsePayload>

<RespString><?xml version="1.0" encoding="UTF-8"?>

<Devices>

<Device>1</Device>

<Name>1</Name>

</Devices></RespString>

</ResponsePayload>

and I need to map it to the target where the target structure is as below .

<?xml version="1.0" encoding="UTF-8"?>

<Devices>

<Device/>

<Name/>

</Devices>

The entire target xml is coming in a source field and that needs to be mapped.

How to perform this?Can any one suggest the methods to do this ?

Thanks

Rajesh
