'year-from-date()' is an unknown XSLT function

[Jon Paal]

getting error message of:
'year-from-date()' is an unknown XSLT function



can anyone help with getting date parts from "$sortFieldName" before sorting.


<xsl:template match="level2">
<xsl:variable name="sortYear" select="year-from-date('$sortFieldName')"/>
<xsl:variable name="sortMonth" select="month-from-date('$sortFieldName')"/>
<xsl:variable name="sortDay" select="day-from-date('$sortFieldName')"/>

<xsl:for-each select="level2">
<xsl:sort select="$sortYear" order="ascending"/>
<xsl:sort select="$sortMonth" order="ascending"/>
<xsl:sort select="$sortDay" order="ascending"/>
<level2>
......
</level2>
</xsl:for-each>
</xsl:template>

Hi,

year-from-date is an XPath 2.0 funtion, see:
http://www.w3.org/TR/xquery-operators/
and you probably are using an XSLT 1.0/XPath 1.0 processor.

Best Regards,
George

XSLT/XPath 2.0 are not yet W3C recommendations, they are on their way to
become specifications. Microsoft so far does not have any products
trying to implement XSLT/XPath 2.0 while the specification is being
developed.

So "enabling" 2.0 is not something that is possible in the XSLT
processors around that implement XSLT 1.0.

One implementation of XSLT 2.0/XPath 2.0 as those specification are
being developed is Saxon 8, see
<http://www.saxonica.com/>

In a stylesheet you simply need e.g.
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0"
