Re: Increment a variable

Hi Chandu,
  The following XSLT 2.0 stylesheet might be helpful (though it
does'nt generate numbers for gridx and gridy properly). I have tested
this with Saxon 8.4.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">

<xsl:output method="xml" indent="yes" />

<xsl:template match="/Parameters">
   <Parameters xmlns:fo="http://www.w3.org/1999/XSL/Format">
     <xsl:for-each select="parameter">
       <xsl:call-template name="generateElem">
         <xsl:with-param name="node" select="." />
         <xsl:with-param name="x" select="position()-1" />
       </xsl:call-template>
     </xsl:for-each>
   </Parameters>
</xsl:template>

<xsl:template name="generateElem">
   <xsl:param name="node" />
   <xsl:param name="x" />

   <xsl:element name="{name($node)}">
     <xsl:attribute name="gridx" select="$x" />
     <xsl:attribute name="gridy" select="$x + 1" />
     <xsl:value-of select="$node" />
   </xsl:element>
</xsl:template>

</xsl:stylesheet>

Regards,
Mukul
