RE: XSLT function optimization - datetime comparisons?

2005-09-21 13:38:25
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>
