Re: Sorting/grouping question

Sure, <xsl:key> would work, I think.

<xsl:output method="text"/>

<xsl:key name="first4digits-are-year" match="date"
use="substring(.,1,4)"/> 

<xsl:template match="/">
 <xsl:for-each
select="/list/date[generate-id()=generate-id(key('first4digits-are-year',substring(.,1,4))[1])]">
  <xsl:sort order="descending" />
  <xsl:text>&#10;</xsl:text>
  <xsl:value-of select="substring(.,1,4)" />
 </xsl:for-each>
</xsl:template>
