I know how to calculate a depth >>from a nodes context, but not the depth of its children. For interest, you can do all of this within an attribute in XPath 2.0: max(for $folder in //folder return count($folder/ancestor::folder)) although possibly the following would be slightly better (depending on the particular pattern of optimisation in the processor): max(for $folder in //folder[not(folder)] return count($folder/ancestor::folder)) Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
