Re: [xsl] grouping and context (?)

Hi Bruce,

If I understand correctly, I think that you want to put a variable in
the top level of the <xsl:template> (before you start doing any
<xsl:for-each-group> stuff) that holds the <db:citation> element
itself. Then you can get to the <db:biblioref> element that you
started from immediately. Something like:

<xsl:template match="db:citation[$citation-class='author-year']">
  <!-- store citation for future use -->
  <xsl:variable name="citation" select="." />
  ...
  <!-- group and sort by authors-string -->
  <xsl:for-each-group select="$bibref" group-by="bib:grouping-key(.)">
    <xsl:sort select="current-grouping-key()"/>
    <!-- within an authors group, sort by year -->
    <xsl:for-each-group select="current-group()"	group-by="mods:year">
      <xsl:sort select="current-grouping-key()"/>
      <xsl:for-each select="current-group()">
      
        ... use $citation here to get back to the original citation ...

   	  </xsl:for-each>
    </xsl:for-each-group>
  </xsl:for-each-group>
</xsl:template>

Does that help?

Cheers,

Jeni
