I have a message I need to be able to parse and convert from XML to Cobol.

The message is made up of the following:

TransmissionHeader - fixed content and size
SegmentData1
SegmentData2
SegmentData3
....

where Segment DataX can:
occur in any order
upto 25 Segment Data occurances
each occurance of SegmentData is a unique structure but fixed

So I can create individual MessageSets for each SegmentData but not one complete MessageSet because until I receive the input message I don't know which one's or what order they will arrive.

I am using XML(XML) for my input message.

I thought about using logic something like this:
1. Parse input message and determine which Segments I need to build
2. Creating a loop within my Flow that loops around a compute node, the node determine which segment to build next and then uses a RouteTo Node to route to a path that:
2.1 Build segment using an MRM message set
2.2 Appends the segment message to the complete message
2.3 Returns to the Compute node Loop
3. The loop would exit when all the segments have been built and then writes the complete message to the output node

This sounds like it would work but not sure about using such a loop withing a Message Flow, also I would imagine performance wouldn't be great.

Any thought on this design or different suggestions how I could create the output message would be greatly appreciated.

thanks
