RE: [xsl] Increment a variable

["Aron Bock" <aronbock@xxxxxxxxxxx>]

Chandrashekar, XSLT variables are not mutable, unlike those in most 
programming laguages -- this follows the thinking in functional languages 
not allowing side-effects.  Thus, doing something repeatedly is usually 
achieved (in XSL 1.0) via recursion.

In your case:

<xsl:template match="/">
   <xsl:call-template name="fun1">
       <xsl:with-param name="end" select="1000"/>
   </xsl:call-template>
</xsl:template>

<xsl:template name="fun1">
   <xsl:param name="end" select="0"/>
   <xsl:param name="start" select="0"/>

   <xsl:if test="$start &lt; $end">
       <xsl:call-template name="fun2"/>
       <xsl:call-template name="fun1">
           <xsl:with-param name="end" select="1000"/>
           <xsl:with-param name="start" select="$start + 1"/>
       </xsl:call-template>
   </xsl:if>
</xsl:template>

<xsl:template name="fun2">
 ...etc
</xsl:template>
