Thanks. This was helpful. We have a xalan.jar which has exsltdatetime
class under that. So we were trying to use that.

Now we started using xalan://java.util.GregorianCalendar and it worked
fine for us.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:cal="xalan://java.util.GregorianCalendar"
                version="1.0">

<xsl:template match="/">
<xsl:variable name="rightNow" select="cal:new()" />
  <html>
  <table>
    <tr>
          <xsl:variable name="year" select="cal:get($rightNow, 1)" />
          <xsl:variable name="month" select="cal:get($rightNow, 2)" />
          <xsl:variable name="date" select="cal:get($rightNow, 5)" />
      <xsl:value-of select="cal:add($rightNow,2,-6)" />
          <xsl:variable name="year1" select="cal:get($rightNow, 1)" />
          <xsl:variable name="month1" select="cal:get($rightNow, 2)" />
          <xsl:variable name="date1" select="cal:get($rightNow, 5)" />
      <tr><td>Current Date : <xsl:value-of
select="$year"/>/<xsl:value-of select="$month"/>/<xsl:value-of
select="$date"/></td></tr>
      <tr><td>After 6 Months : <xsl:value-of
select="$year1"/>/<xsl:value-of select="$month1"/>/<xsl:value-of
select="$date1"/></td></tr>
    </tr>
  </table>
  </html>
</xsl:template>

</xsl:stylesheet>

Hi Nagendra,

I use exslt dates-and-times functions by importing the XSLT
implementation
as named templates, so for example:


   <xsl:stylesheet version="1.0"

      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:date="http://exslt.org/dates-and-times"
      exclude-result-prefixes="date"      >

   <xsl:include href = "exslt/date.add.template.xsl" />



   <xsl:template match="/">
      <xsl:call-template name = "date:add">
            <xsl:with-param name = "date-time"  select = "'2000-01-01'"
/>
            <xsl:with-param name = "duration"   select = "'P20D'" />
      </xsl:call-template>
   </xsl:template>


   </xsl:stylesheet>

- should work just fine (note, in this example, the exslt script is
located
in a 'exslt' sub-directory). It's not as neat as defining an extension
function (I don't have any experience of doing this with Xalan-J; I'm
not
sure if it's supported), but has the advantage of portability - I'm
writing
code to run under both Xalan and MSXML.

I guess you read the advice on using extension functions at
http://www.exslt.org/howto.html?

Best regards,
Harry

Hi,


I am trying to use the date-and-times package to get current date and 6
months back date. The date:add function to add duration to date is
giving
the following error. Any idea what could have gone wrong.


->java org.apache.xalan.xslt.Process -in test.xml -xsl test.xsl

<xsl:template match="/">

</xsl:call-template>
</xsl:template>
</xsl:stylesheet>
