I've been stuck on the next problem for a few days now, eventhough the answer must be real simple ( I think), I cant figure it out. Multiple-level sorting with the pure Muenchian method involves divining a key combination that is unique at each level of the key sort and then recombining this for each node being tested. Personally, I find that sorting sub-groups is a lot easier using variables instead of using key tables. You don't give enough data to write a quick test file, but here is the outline of the code structure: <xsl:variable name="firsts" select="XPath-of-first-level-sort-nodes"/> <xsl:for-each select="$firsts"> <xsl:if test="generate-id(.)= generate-id($firsts[XPath-of-unique-value-calculation])"> <!--first-level grouping completed--> <xsl:variable name="seconds" select="XPath-relative-for-seconds"> <xsl:for-each select="$seconds"> <xsl:if test="generate-id(.)= generate-id($seconds[XPath-of-unique])"> <!--second-level grouping completed--> ...etc.... </xsl:if> </xsl:for-each> </xsl:if> </xsl:for-each> I hope the above helps. ...................
