[xsl] Applying a Second Stylesheet to a Stylesheet's Results

["petefc@xxxxxxxxxxxxxxxxx" <pcharles@xxxxxxxxxxxxx>]

Hello,

If in style-sheet-one.xsl, I capture the output of an apply-templates
as a variable:
  <xsl:variable name="foo">
            <result>
                <xsl:apply-templates/>
            </result>
  </xsl:variable>

Is there a way for me to run a second style-sheet-two.xsl against the the
$foo variable, in such a way that all templates from style-sheet-one.xsl
are no longer valid?

Thanks,

Peter
