Thanks Ken--returning a node-set from the tables in all files instead of
iterating through each file seems to make more sense.  However, that does
present a secondary grouping problem--your stylesheet outputs a separate
country node for each city.  I think combining your approach with Niko's
suggestion of doing a second pass on the output (and using a key) will do
the trick.

thanks again,
