Your use of [@dataid = current()/@dataid] provided the missing clue: <xsl:for-each select="(//dataset/*/*[generate-id() = generate-id(key('dataids', concat(local-name(..),@dataId)))])"> <xsl:sort select="parent::node()/*[local-name() = $sortcol and @dataId = current()/@dataId]/value"/> The real life version is somewhat more complicated in that it has to skip certain values and the name of the "value" node is dynamically picked from a list based on the sort column, but it all works. Now I get to define optional ascending or descending dependant on the column picked. The last step is to look at using more keys. I'd still like to know if I can use a key or some combination of keys to eliminate the //dataset reference in the for-each...(anyone)???
