Re: [xsl] grouping/position problem

[Bruce D'Arcus <bdarcus@xxxxxxxxx>]

Actually, I need to correct two things on my reply to Mike; first the 
template needs to put the year variable within the year-grouped 
for-each (it was outside the for-each).  So:

   <xsl:template match="list" mode="sort_author-year">
     <xsl:for-each-group select="item" group-by="@author">
       <xsl:sort select="current-grouping-key()"/>
       <xsl:for-each-group select="current-group()" group-by="@year">
         <xsl:sort select="current-grouping-key()" />
         <xsl:for-each select="current-group()">
	   <xsl:variable name="year">
              <xsl:value-of select="current-grouping-key()"/>
	       <xsl:if test="last() > 1">
	         <xsl:number value="position()" format="a"/>
	       </xsl:if>
	   </xsl:variable>
           <xsl:variable name="author-position" select="position()"/>
           <xsl:variable name="shorten-author" 
as="xs:boolean"select="$author-position > 1" />
           <xsl:apply-templates select=".">
             <xsl:with-param name="year" select="$year"/>
             <xsl:with-param 
name="shorten-author"select="$shorten-author"/>
           </xsl:apply-templates>
         </xsl:for-each>
       </xsl:for-each-group>
     </xsl:for-each-group>
   </xsl:template>

Therefore this is wrong:

> <result>
>    <item>
>       <shorten-author>false</shorten-author>
>       <year>2001a</year>
>    </item>
>    <item>
>       <shorten-author>true</shorten-author>
>       <year>2001a</year>
>    </item>
>    <item>
>       <shorten-author>true</shorten-author>
>       <year>2002b</year>
>    </item>
> </result>

It should be:

<result>
   <item>
      <shorten-author>false</shorten-author>
      <year>2001a</year>
   </item>
   <item>
      <shorten-author>true</shorten-author>
      <year>2001a</year>
   </item>
   <item>
      <shorten-author>true</shorten-author>
      <year>2002</year>
   </item>
</result>

Note the last year.
