Re: One problem using Date:add utility from exslt

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


file:///home/mallin/test.xsl; Line #11; Column #57; XSLT Error
(javax.xml.transform.TransformerConfigurationException):

date:add('2000-01-01','P20D') used for QNAME attribute: name

                xmlns:date="http://exslt.org/dates-and-times"
                extension-element-prefixes="date"
                version="1.0">


<xsl:template match="/">
<xsl:call-template name="date:add('2000-01-01','P20D')">
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>


Thanks
