Hi Chris,
you did import the exslt date stylesheet, didn't you?
(I don't see it in your fragment):
<xsl:import href="date.xsl" />
If you didn't, your stylesheet will know nothing about the named extension
templates (in other words, you're calling templates that don't exist)
But I suppose you did import it... Then take a look at your template calls:
<xsl:call-template name="date:hour-in-day"/>
You are calling the template with no parameters! How can the template
know what date/time you want to extract the hours of?
You will need something like:
<xsl:call-template name="date:hour-in-day">
<xsl:with-param name="date-time" select="$date-str"/>
</xsl:call-template>
If you want the current system time, you will need to call the
appropriate function "date:date-time()".
(see http://www.exslt.org/date/functions/date-time/index.html)
HTH,
Anton Triest

Subject: [xsl] EXSLT extension function
Hi everybody!
I'm trying to pull in the system time (I'll want the date as well, but one
thing at a time...)
to my XSLT stylesheet. It looked like the EXSLT functions had just what I
need, and
they're supposedly supported by my XSLT processor (Xalan-J 2.6). But I'm
getting this
error:
javax.xml.transform.TransformerException: ElemTemplateElement error:
date:hour-in-day
I might have the namespace wrong or perhaps I'm not calling the extension
function
correctly? I've done a Google search without finding anything. Anybody have
any
ideas? Thanks!
Here is a fragment of the stylesheet (I know it's not well-formed -- I'm
just copying the relevant section):
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:date="http://exslt.org/dates-and-times";
extension-element-prefixes="date">
<xsl:output method="xml" version="1.0" omit-xml-declaration="yes"
indent="yes" />
<xsl:template match="BillHeader">
<xsl:variable name="time">
<xsl:variable name="hours">
<xsl:call-template name="date:hour-in-day"/>
</xsl:variable>
<xsl:variable name="minutes">
<xsl:call-template name="date:minute-in-hour"/>
</xsl:variable>
<xsl:value-of select="concat($hours,$minutes)"/>
</xsl:variable>
etc.
Yours,
Chris Loschen
