xml-into

Hi,

Not having much fun using XML-INTO and nested DS arrays :-(

I need an array at the end something like this
fileIn(1).header.file_number = 31
fileIn (1).contract(1).num_contract = 741
fileIn (1).contract(2).num_contract = 750
fileIn (2). header.file_number = 42
fileIn (2).contract(1).num_contract = 850
fileIn (2).contract(2).num_contract = 950

I've tried pulling the whole of my xml file into 1 DS (this came out
empty, I'm not sure if XML-INTO knows how to do this).
I can get the "header" elements into one DS array and the "contract"
elements into another :

Header(1). file_number = 31
Header(2). file_number = 42

contract(1).num_contract = 741
contract(2).num_contract = 750
contract(3).num_contract = 850
contract(4).num_contract = 950

Obviously that's not good as I've lost the relation
file_number/num_contract.

Thanks for any help.
