This isn't probably much help - based on the attached results, I can
only really suggest you try Saxon.

The template match you suggested is correct, and this may well be a bug
in XT - it definitely produced different results from Saxon.

Here's my input, XSLT and output.

---- input ----
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE document>

<document>
  <doc>
    <div>doc1-div1</div>
    <div>doc1-div2</div>
  </doc>
  <doc>
    <div>doc2-div1</div>
  </doc>
  <doc>
    <div>doc3-div1</div>
    <div>doc3-div2</div>
    <div>doc3-div3</div>
  </doc>
</document>

--- xslt ----
<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="doc/div[last()=1]">
  <xsl:value-of select="." />
  <xsl:text> (</xsl:text>
  <xsl:value-of select="position()" />
  <xsl:text> - </xsl:text>
  <xsl:value-of select="last()" />
  <xsl:text>)
</xsl:text>
</xsl:template>

<xsl:template match="text()" />

</xsl:stylesheet>

---- output with saxon 5.3.2 ----
<?xml version="1.0" encoding="utf-8" ?>
doc2-div1 (2 - 3)

---- output with xt 19991105 ----

<?xml version="1.0" encoding="utf-8"?>
doc1-div1 (2 - 5)
doc3-div2 (4 - 7)

Really wierd!

I've asked this before, but can someone explain why position()
and last() give the results they do in the Saxon output?
