This can be easily modified to do a bunch of other things.. You can use a external generated document for big interations, but it's not very performant, i think, 2 parses... Perhaps somebody finds that useful..( at least it's usefull for me :) My 0.02 ? ( nothing compared to the income i've got from the xsl-list :) Saludos , Ignacio J.
