Re: XPath 2.0 function polymorphism
You should look at Dimitre's FXSL library; he has elevated using elements to act as proxies for functions into an art form:-) For literals, since there are not so any base types (although there could be a lot less) you can probably just use xsl:choose, something like: <xsl:function name="ns:func"> <xsl:param name="arg" as="node()"/> <xsl:choose> <xsl:when test="$arg instance of xs:integer"> <xsl:sequence select="ns:func-integer($arg)"/> </xsl:when> <xsl:when test="$arg instance of xs:string"> <xsl:sequence select="ns:func-string($arg)"/> </xsl:when> ... <xsl:otherwise> <xsl:apply-templates select="$arg" mode="ns:func"/> </xsl:otherwise> </xsl:choose> </xsl:function> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
