I've done this the simple way ("with lots of coding" - about 8 lines), by
concatenating the query results into a single XML document and then parsing
it. I've thought about other techniques, like embedding the SQL queries into
the document in some way (an entity? an element? a PI?) and replacing each
query with its result in the course of parsing, but haven't got round to
implementing anything.
