Do you mean that the CURRENTNODE element within your source document
holds the string 'TRAVELNODE', and you want to find the element named
that, and process its children?

If so, then you need:

  <xsl:for-each
    select="LIBRARY/*/*[name() = //LIBRARY/CURRENTNODE]/*">
    <TR valign="center">
      <TD>
        <xsl:value-of select="NAME" />
      </TD>
    </TR>
  </xsl:for-each>

Alternatively, especially if what's held in the CURRENTNODE element is
more complicated than just the name of an element, you can use an
extension evaluate() function, but I'd avoid those if you can.

Cheers,

Jeni
