A quick and dirty way:

<xsl:if test="position() = 1">
        <div>
            <xsl:value-of select="AgencyName"/>
      </div>
</xsl:if>

This will display AgencyName only on the first occurrence of the nodes
selected by your key.

Not really. It'll display AgencyName only if the current node of the instruction is the first node among the current node list -- something which only has to do with the order of the nodes you select by your key if you control for this. If you don't, and it works, it's working by accident.


  Note, however, that your key only groups by
FilingType--if you have multiple AgencyNames with the same FilingType
only the first occurrence of AgencyName will appear.

You can fix this by expanding your key:

  <xsl:key name="tar_by_filingtype" match="MonthlyTARList"
use="concat(FilingType, ' ', AgencyName)"/>

Then change your for-each to use

key('tar_by_filingtype', concat(FilingType, ' ', AgencyName))

Using an explicit for-each instruction around the xsl:if clause will provide the needed control to make sure position() works properly ... but it's then safer just to select the first one in document order explicitly:


<xsl:for-each
  select="key('tar_by_filingtype', concat(FilingType, ' ', AgencyName))[1]">
  <!-- note predicate in select expression -->
  <div>
    <xsl:value-of select="AgencyName"/>
  </div>
</xsl:for-each>

Cheers,
Wendell
