Hi, I have a basic requirement but cannot find a way to do that in TDM. For instance, I have an input file like : <ROOT> <POs> <PO> <Number>1</Number> </PO> <PO> <Number>2</Number> </PO> </POs> <ORDERs> <ORDER> <Num>3</Num> </ORDER> <ORDER> <Num>4</Num> </ORDER> </ORDERs> </ROOT> And I want to merge the two loops to get in the output file : <ROOT> <POs> <PO> <Number>1</Number> </PO> <PO> <Number>2</Number> </PO> <PO> <Number>3</Number> </PO> <PO> <Number>4</Number> </PO> </POs> </ROOT> I cannot figure out out how to do that because the output loop cannot mix both input loop. If someone has suggestions that would be great ? Regards. Eric
