Xalan ESLT function date:date-add
Hello,
This XSLT:
<?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" >
<xsl:import href="date.add.function.xsl" />
<xsl:output method="xml"/>
<xsl:param name="p_dagen_terug"/>
<xsl:template match="onderwerpen">
<xsl:variable name="d1"><xsl:value-of
select="date:date()"/></xsl:variable>
<xsl:variable name="d2"><xsl:value-of select="substring-before
($d1, '+02:00')"/></xsl:variable>
<xsl:variable name="d5"><xsl:value-of
select="date:date-add($d2,'-P50D')"/></xsl:variable>
<basis>
1
<xsl:value-of select="$d1"/>
2
<xsl:value-of select="$d2"/>
5
<xsl:value-of select="$d5"/>
</basis>
</xsl:template>
</xsl:stylesheet>
Gives this error;
org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
java.lang.RuntimeException: java.lang.RuntimeException:
java.lang.NullPointerException
I'm not sure if Xalan supports this EXSLT function natively , but with
'import' I was hoping to use this EXSLT function anyway
by the way: without the 'import' line I get the same error...
The 'imported' file is downloadable from www.exslt.org

Thank you,
You are right, java gives a lot of power.
I also discovered that some exslt functions are not implemented (yet)
in Xalan, as in almost no important
To use the external functions (being the xslt version og Jeni Tennison
or the Java stuff thats on the www.exslt.org site i needed to change
the namespace to make clear distiction between the 'included in xalan'
versus the 'not included in Xalan'

Re: Xalan ESLT function date:date-add
Posted by Jan Hoskens <jh...@schaubroeck.be>.
If you're trying to work with dates, you can use the java extensions in
xalan. This way you can call any java stuff you need.
namespace to include:
xmlns:java="http://xml.apache.org/xslt/java"
<xsl:variable name="locale"
select="java:java.util.Locale.new('nl','BE')"/> <!-- Class.new creates
new instance -->
<xsl:variable name="currentCalendar"
select="java:java.util.Calendar.getInstance($locale)"/> <!-- static
factory method -->
<xsl:variable name="currentDate" select="java:getTime($currentCalendar)"/>
<xsl:variable name="dateFormat"
select="java:java.text.DateFormat.getDateTimeInstance(java.text.DateFormat.MEDIUM,
java.text.DateFormat.MEDIUM, $locale)"/>
<xsl:variable name="TimeStamp" select="java:format($dateFormat,
$currentDate)"/> <!-- normal functions, first give object on which to
perform the function, then arguments-->
Kind Regards,
Jan
