Hi!
I was thinking like this:
1) Create 2 DataSource steps, both referring to the same file but different sheets and each with their corrsponding properties (start_date and end_date)
2) Refer to these 2 values using standard property-expansion in your request, ie something like:
<startDate>${DataSource 1#start_date}</startDate>
<endDate>${DataSource 2#end_date}</endDate>
makes sense?
