This creates a variable called $sortedErrorMessage which contains the
*values of* the Name, Type and Details elements, in order. Note that
it doesn't contain any elements.

The msxsl:node-set() function converts the result tree fragment to a
node set and returns the root node of that node set. You're then
looking for Name child elements of the root node - there aren't any
because you didn't create any.

I think that you should change the way that you create the variable.
Try using:

  <xsl:variable name="sortedErrorMessage">
    <xsl:for-each select="/ErrorMessages/ErrorMessage">
      <xsl:sort select="Name" order="ascending" />
      <xsl:sort select="Type" order="ascending" />
      <xsl:copy-of select="." />
    </xsl:for-each>
  </xsl:variable>

That creates copies of the ErrorMessage elements, and the
$sortedErrorMessage variable's root node has several ErrorMessage
children, in order. Then you can do:

  <xsl:for-each
      select="msxsl:node-set($sortedErrorMessage)/ErrorMessage">
    <xsl:value-of select="Name"/>
  </xsl:for-each>

For example.

I hope that helps,

Jeni
