applying templates on variables

[Ovidiu Predescu <ov...@cup.hp.com>]

The following template does not work with Xalan 1.2.1, while it works fine with
Saxon 5.5.1:

 <xsl:template match="page[split]">
  <xsl:variable name="page">
   <page>
    <xsl:copy-of select="@*"/>
    <xsl:copy-of select="child::*[preceding::split]"/>
   </page>
  </xsl:variable>
  <xsl:apply-templates select="$page"/>
 </xsl:template>

The first error I got was an exception as XRTreeFrag object could not be
converted to a NodeList. This was easily fixed by defining the nodeset()
method; here is a patch that does it:

However it looks like Xalan still doesn't want to properly apply the templates
to the DOM tree kept in the $page variable. Any ideas what could be wrong?

Your patch does not properly implement the nodeset() extension.  You
should use the one supplied with Xalan itself.  A result tree fragrment
is equivalent to a node-set consisting of a single node that is the root
node of the result tree.  Your patch creates a node-set consisting of
all of the child nodes in the RTF.

Try this with the built-in nodeset extension and let us know if that
works.
