Not being sure what your requirements are, I've found that this change, as
close to the original solution, does the trick:
...
<xsl:copy-of select="Location/Element" copy-namespaces="no"/>
<Description>
<xsl:for-each select="current-group()">
<xsl:if test="not(Location/Element/following-sibling::SubDiv)">
<xsl:copy-of select="Data" copy-namespaces="no"/>
</xsl:if>
</xsl:for-each>
</Description>
<xsl:for-each-group select="current-group()"
group-by="Location/SubDiv">
...

Hi all,
I have been at this for about six hours.
As written, the style sheet does not produce the element marked "Missing
element" in Listing 3 (the output ) and as "Not output" in Listing one
(source document). The problem is marked "My problem" in the Listing 2 (style
sheet).
I Know that my problem is that I am telling the style sheet to give me only
the first <Data> element. What I don't know is how to tell it to give me all
of the <Data> elements that meet the <xsl:if> test, but none of the <Data>
element that do not meet that test. Or have I just set everything up wrong to
start with?
Any help would be appreciated
Mark
