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, b. | brian martinez brian.martinez@xxxxxxxx | | senior gui programmer 303.708.7248 | | trip network, inc. fax 303.790.9350 | | 6436 s. racine cir. englewood, co 80111 | | http://www.cheaptickets.com/ http://www.trip.com/ | XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
