Re: How to pass an XPath as a param and evaluate it?

   <xsl:output method="xml" indent="yes"/>
   <xsl:param name="xpath"/> <!-- passed on command line as a param -->

   <xsl:template match="/">
           <xsl:copy-of select="saxon:evaluate($xpath)"/>
   </xsl:template>
</xsl:stylesheet>

Thanks so much,

Is there a function or syntax in XSLT 1 or 2 that will evaluate the XPath at run-time?

No, but there is in XSLT 3.0 (formerly known as XSLT 2.1). See

http://www.w3.org/TR/xslt-21/#element-evaluate

To use this in Saxon 9.3 you will need to activate XSLT 3.0 using -xsltversion:3.0

Come to think of it, I think that might require Saxon-EE. In Saxon-PE you might have to fall back to the saxon:evaluate() extension.
