Im going to use this variable later on. I try to rewrite my code.

I think this is not going to work. The parameter articleperpage gets later on
a value based on 2 parameters.

Oke,



What I was trying to make this part :



<!-- Named template definition: printdata -->
 <xsl:template name="printdata">
 <xsl:param name="articleperpage"/> <!-- parameter declaration -->

<!-- Template logic -->

</xsl:template>

<xsl:call-template name="printdata">
 <xsl:with-param name="articleperpage"> <!-- parameter value to pass to named
template -->
 <xsl:choose>
 <xsl:when test="($month = '2005-02') and (number($page) = 1)">2</xsl:when>
 <xsl:when test="($month = '2005-02') and (number($page) = 2)">3</xsl:when>
 <otherwise>1</otherwise>
 </xsl:choose>
 </xsl:with-param>
 </xsl:call-template>

to work into this template :



<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml"
 doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
 doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
 omit-xml-declaration="yes"
 encoding="UTF-8"
 indent="yes" />



<xsl:variable name="mycount" select="count(/data/artikel-details/entry)" />



<xsl:template match="/">
    <xsl:apply-templates select="/data/artikel-details/entry"/>
</xsl:template>



<xsl:template match="artikel-details/entry">
   <h1><xsl:value-of select="titel"/></h1><br />
    <xsl:value-of select="datum" /><br />
    <xsl:value-of select="tekst" /> <br />
</xsl:template>


</xsl:stylesheet>



But I did it appearently very wrong.

The are declared by Symphomny CMS which I use to make this website.
