Hi All,
Is there any wayout for calculating no. of years with a given date and current date in BPEL.
I am developing a small application where I have to calculate the years of experience of the employees. I am given with the date of joining.I want to subtract the date of joining from the current date. Is there any way-out to calculate no. of years from the given date and current date in BPEL using date functions or something else.
Please suggest something..

you could use something like this in xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">
     <xsl:output method="xml"/>
     <xsl:variable name="date1" select="xs:date('2001-01-01')"/>
     <xsl:variable name="date2" select="xs:date('2010-01-10')"/>
     <xsl:variable name="dif" select="$date2 - $date1"/>
     <xsl:template match="/">
     <all>
          <date1>
               <xsl:value-of select="$date1"/>
          </date1>
          <date2>
               <xsl:value-of select="$date2"/>
          </date2>
          <dif-days><xsl:value-of select="fn:days-from-duration($dif)"/></dif-days>
          <dif-years1><xsl:value-of select="fn:years-from-duration($dif)"/></dif-years1> <!-- gives 0 for me -->          
          <dif-years2><xsl:value-of select="fn:days-from-duration($dif) div 356"/></dif-years2>                    
          </all>
     </xsl:template>
</xsl:stylesheet>
