Error on line 2 of document : Content is not allowed in prolog. Nested exception: Content is not allowed in prolog.
I still think the solution with get nodes should work.
Join this by a main row into tFilterRow:
I uncheck the "Create empty element if needed" option, so the fields that are empty won't be shown. This gives me the right result, but if I do want some fields that are empty to appear, this solution will not work anymore.
