Tom,
I finally found the answer. 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)???
