updating/inserting into a CSV, XML, or whatever flat file will be very
painful, it will require copying the whole file with the new/changed
record in place.
I would recommend instead importing your XML/CSV/etc data into SQL
table(s), do your data operations there, then export the results back as
XML or whatever if you really need it that way.
