Question

I have an XSL template that is selected for execution (below). What I would like to do is be able to tell if I am the last Unit being matched.

  <xsl:template match="Unit[@DeviceType = 'Node']">
    <!-- Am I the last Unit in this section of xml? -->
    <div class="unitchild">
      Node: #<xsl:value-of select="@id"/>
    </div>
  </xsl:template>

Example XML

<Unit DeviceType="QueueMonitor" Master="1" Status="alive" id="7">
    <arbitarytags />
    <Unit DeviceType="Node" Master="0" Status="alive" id="8"/>
    <Unit DeviceType="Node" Master="0" Status="alive" id="88"/>
</Unit>

Answer 1

If you want to test whether it is the last Unit element at the same level (with the same parent element), even if there are arbitrary tags before, after, and in-between then this would work:

<xsl:if test="not(following-sibling::Unit)">

However, if you are applying templates for a subset, the last in the document may not be in the set being processed. For that, you can test if the position() = last()

<xsl:if test="position() = last()">
