Repeating sections - how to get the data

[Bards]

My question is about how to get at the data you caputure in a repeating section in NWC.

I know this is a new control, so there may be no answers yet, however in O365 you write the data from a repeating section control to a Multi-lines of text field then parse the XML with with a 'Query XML' action to pull that apart. However, in NWC the repeating section seems to store the data as a Collection/array, not as XML. So, I would have thought you could use Collection operations on that. Not so it would seem: I can use 'Count items in collection' to get the number of sections, but I have tried and failed to use 'Get item from collection' to get values. Not that I can see how that would work anyway - what type of variable do you use to store different data types (say, text and a number) from a section?

In case I'm missing something here I'd love to hear from someone to let me know. As it is, I can't see what use repeating sections in NWC have if I can't do anything with the data captured.

An update for anyone interested.

Through testing I've found you can use the 'Apply a regular expression' WF action to get at data in a section. This is a bit cumbersome however: you need to count the items in the Collection and then for each section run multiple RexEx actions to get each variable/field from each section. 

Again, I would be happy to hear from anyone else if I'm missing something here and there's a better or easier way to get at the data.
