Only using an extension function. You can store the result of the
first pass in a variable, but it's stored as a result tree fragment,
which means that you can't go on to process it further without turning
it into a node set. You can turn it into a node set with extension
functions; most processors have them...

... and in Xalan-C++ it's called nodeset(), in the namespace
http://xml.apache.org/xalan. So do something like:

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xalan="http://xml.apache.org/xalan"
                extension-element-prefixes="xalan">

<xsl:template match="/">
  <xsl:variable name="pass1-rtf">
    <xsl:apply-templates mode="pass1" />
  </xsl:variable>
  <xsl:apply-templates select="xalan:nodeset($pass1-rtf)"
                       mode="pass2" />
</xsl:template>

...

</xsl:stylesheet>

with templates in 'pass1' mode for your first pass and in 'pass2' mode
for your second pass.

Cheers,

Jeni
