Re: [xsl] Sorting seems not to work completely

Thanks Martin,
I believe I am using the free version of Saxon 9 (but did not know how to 
obtain the version number directly) called in a windows batch file with the 
command :
java  -jar c:\Users\HP\saxon\saxon9.jar    xml\all-themes.xml 
xslt\get-dates.xsl    > work\dates.xml
The template, a selection of the input file, and the corresponding selection 
from the output file appear below.
Thanks,
Mark

Again, my template is:

<xsl:template match="List">
   <xsl:element name="List">
    <xsl:for-each-group select="Item/Stamp" group-by="concat(Date/@year, ' 
', Date/@month, ' ', Date/@day)">
      <xsl:sort select="Date/@year" data-type="number"></xsl:sort>
      <xsl:sort select="Date/@month" data-type="number"></xsl:sort>
      <xsl:sort select="Date/@day" data-type="number"></xsl:sort>
      <xsl:sort select="@value" order="descending" 
data-type="number"></xsl:sort>
      <xsl:element name="Item">
        <xsl:copy-of select="current()/Date" 
copy-namespaces="no"></xsl:copy-of>
        <xsl:copy-of select="current-group()" 
copy-namespaces="no"></xsl:copy-of>
      </xsl:element>
      </xsl:for-each-group>
   </xsl:element>
 </xsl:template>

A suitable selection of the input file [edited to remove <Stamp>'s numerous 
sibling elements not involved in this process]:

I don't see anything wrong with the snippets you posted. You might want
to provide more details such as an input sample you are trying to group
and sort, the result you get, the one you want, and details of the XSLT
processor you used, so that we can reproduce the problem.
