Receive HL7 messages (flat file) in orchestration

Hi,

I have been struggling the last couple of days to try to process HL7 files in an orchestration.  I receive 25 HL7 (ORU-R01) in a batch from a web service.  The output message from the webservice is like below:

Batch (Root)
– Batch ID
– Msg QTY
– HL7Messages
-HL7Message (Element – string)  (qty=25)

These messages are pure string, no xml at all. I can successfully unbatch the messages.  At the end, I loop through the messages and I was planning to call a Receive Pipeline to transform each message via the BTA2.X dissasembler in the orchestration.  However, the receive pipeline take a XLANG message as an argument, and I was not able to find an elegant way to transform a string into XLANG. I want to to keep this process in the orchestration since I have post-processing operations to perform on these messages, and I will use direct bound orchestration.

1) Is this approach the right one? If so, what part am I missing?

2) If not, what approach should I use?

Thanks for your time.
