xsl:function doesn't exist in XSLT 1.0, but it does exist in XSLT 2.0. Xalan is a version 1.0 processor, while Saxon 8.x is a version 2.0 processor. That's why it works with Saxon but not with Xalan.

I'm using Saxon - I found that Xalan (2.7) just couldn't do this sort of thing for reasons I don't understand to this day.

<xsl:function name="my:compDate" as="xs:boolean"> <xsl:param name="dt_a" as="xs:string" /> <xsl:param name="dt_b" as="xs:string" /> <xsl:choose> <xsl:when test=" xs:integer(translate(translate(translate($dt_a,'-',''),'T',''),':','')) gt xs:integer(translate(translate(translate($dt_b,'-',''),'T',''),':',''))"> <xsl:copy-of select="true()"/> </xsl:when> <xsl:otherwise> <xsl:copy-of select="false()"/> </xsl:otherwise> </xsl:choose> </xsl:function>
