Re: How to do this without updating a variable?

Hi Anupam,
   Please try this stylesheet

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

<xsl:output method="text" />

<xsl:template match="/">
   Node: Start End
   <xsl:for-each select="//reg">
     <xsl:value-of select="." />:
     <xsl:choose>
       <xsl:when test="position() = 1">
         1
       </xsl:when>
       <xsl:otherwise>
         <xsl:value-of select="sum(preceding::reg/@count)+1" />
       </xsl:otherwise>
     </xsl:choose> -
     <xsl:choose>
       <xsl:when test="position() = 1">
         <xsl:value-of select="@count" />
       </xsl:when>
       <xsl:otherwise>
         <xsl:value-of select="@count + sum(preceding::reg/@count)" />
       </xsl:otherwise>
     </xsl:choose>
   </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Mukul
