Can anyone recommend an approach for traversing a MRM parsed message whereby the message contains optional structures.

For example say you have a message with the following tree structure:
InputRoot.MRM.type0 (optional repeating structure)
InputRoot.MRM.type1 (optional repeating structure)
InputRoot.MRM.type2 (optional repeating structure)
InputRoot.MRM.type3 (optional repeating structure)
InputRoot.MRM.type4 (optional repeating structure)

Is there a way to count the total number of InputRoot.MRM.type(s) and then based on
1) the total number of InputRoot.MRM.type(s)
2) contents of the type split the data(propagate) into smaller messages.

Keep in mind that functions such as CARDINALITY are not applicable unless you wanted to perform CARDINALITY on each optional InputRoot.MRM.type* and add them up ... also want to preserve InputRoot.MRM.type(s) order on the output message

There's a good set of sample code in the information center about accessing fields using anonymous references.

You could also look a bit closer at the SELECT function.

...Anonymous field references and use of "FIELDNAME(InputBody.*[I])" did the trick!

Thx for the suggestion
