Extract data from JDBC step

I'm looking to do something similar. I'm not sure how to go about capturing the output but from what you are describing It sounds like you are capturing the data. I doubt if the data is in an array. It is most likely a list and the two are manipulated syntactically different.

Try adding subscripts to your xpath (0, 1, 2) and see if you can display each description in the response. If you can than I would think that a simple loop would allow yo to iterate through.

Maybe a piece to the puzzle!

You could use XQuery assertion like this

Or a script assertion to create a list array
