xsl check node empty
      Thank you. That worked a treat! I said it would be something so
      Thanks for your rapid response to my question.


Hi jeremyf,

>       </node>

That's an element called 'node' with a single text node child (the
text node is just whitespace, but it still counts as a text node
unless you're stripping spaces?).

I suspect that you want to test whether the 'node' element contains
any element children, in which case the test should be:

<xsl:template match="node">
            <xsl:when test="*">
                  'node' element has child elements
                  'node' element doesn't have child elements

But you might mean any one of:

  test="node()"                 -- any child nodes
  test="* or text()"            -- any element or text children
  test="* or normalize-space()" -- any element or text aside from

I hope that one of those fulfills your requirements.
