RE: passing a string as a node list


Hi,

I know it works with Xalan-J 2_0_1 and I am using it successfully. Here is a
snippet of XSL code you may need to implement it.

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
			      xmlns:xalan="http://xml.apache.org/xalan";
exclude-result-prefixes="xalan">
  <xsl:template name="paramproc">
    <xsl:param name="evalparam"/>
  <!-- change context node -->
      <xsl:for-each select="$chandoc">
	'<xsl:value-of select="normalize-space(xalan:evaluate($evalparam))"
/>'
      </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>

Saxon also has the same extension function called evaluate which in fact was
implemented earlier. Depends which processor you choose to use. Hope this
helps.

Ta, Tom.

I've found mention of the xalan:evaluate() extention a few times but 
the xml.apache.org says it's not implemented yet.  Anyone know if it's 
been done in the CVS?

Thanks, Tim.
