InfoPath Dev

in my on task change event I submit a info path form that has a repeating section with 7 fields in it.  I can get the string from the ExtendedProperties field but I am only getting the last section of the repeating section. Is there anyway to get all the sections

the easiest way is to use additional fields that will have concatenated values of the repeating table and promote that field.

I can get to all the fields in the repeating section. The problem Im having is when I submit the form to the workflow I might have filled out 3 repeating sections. Only the last sections that I filled out will be in the xml. The first two sections that I filled out are missing. How do I find all the repeating sections that I filled out.
