xml - How to use node-set function in a platform-independent way?

Question

I'm writing some xlst file which I want to use under linux and Windows. In this file I use node-set function which declared in different namespaces for MSXML and xsltproc ("urn:schemas-microsoft-com:xslt" and "http://exslt.org/common" respectively). Is there any platform independent way of using node-set?

Answer 1

You can use the function function-available() to determine which function you should use:

<xsl:choose>
  <xsl:when test="function-available('exslt:node-set')">
    <xsl:apply-templates select="exslt:node-set($nodelist)" />
  </xsl:when>
  <xsl:when test="function-available('msxsl:node-set')">
    <xsl:apply-templates select="msxsl:node-set($nodelist)" />
  </xsl:when>
  <!-- etc -->
</xsl:choose>

You can even wrap this logic in a named template and call it with the nodeset as a parameter.
