Re: Adding numbers in xsl loop

like
..in the example... given by Ard,
if the required result follows the logic
$totaalX+i ( where i = 1 to no of times loop runs,)

( as long as this is what Ard needs.... )

Something like this:

> <xsl:variable name="totaalX"
select="sum(../../hours/entry[login=$loginMatch][date/year=$jaarX][date/mont

hehe, another customer !

u cant do x=x+1 loops with XSLT, because once u set a var it cannot change !

u can get around this quite easily by having a named template and call it
recursively eg.

taken straight from cooktop

<!-- Use: include this call with the number of iterations
 This sample will loop from 1 to 10 including 1 and 10
-->
<xsl:call-template name="for.loop">
 <xsl:with-param name="i">1</xsl:with-param>
 <xsl:with-param name="count">10</xsl:with-param>
</xsl:call-template>
<!-- Rename "old name" elements to "new name" -->
<xsl:template name="for.loop">
 <xsl:param name="i"/>
 <xsl:param name="count"/>
 <xsl:if test="$i &lt;= $count">
<!--    body of the loop goes here    -->
 </xsl:if>
 <xsl:if test="$i &lt;= $count">
  <xsl:call-template name="for.loop">

   <xsl:with-param name="i">
    <!-- Increment index-->
    <xsl:value-of select="$i + 1"/>
   </xsl:with-param>
   <xsl:with-param name="count">
    <xsl:value-of select="$count"/>
   </xsl:with-param>
  </xsl:call-template>
 </xsl:if>
</xsl:template>
