Hi Jan,
  Please try the following stylesheet:

   <xsl:template match="/theExampleXMLTree">
       <xsl:text>NodeNr.|Value &#xa;</xsl:text>
       <xsl:for-each select="Node">
           <xsl:variable name="count">
              <xsl:call-template name="XYZ">
                 <xsl:with-param name="nodeset"
select="following-sibling::*" />
                 <xsl:with-param name="n" select="0" />
             </xsl:call-template>
           </xsl:variable>
           <xsl:value-of select="position()" />|<xsl:value-of
select="$count" /><xsl:text>&#xa;</xsl:text>
       </xsl:for-each>
   </xsl:template>

   <xsl:template name="XYZ">
       <xsl:param name="nodeset" />
       <xsl:param name="n" />

       <xsl:choose>
           <xsl:when test="$nodeset[1]/@count-me = 'yes'">
               <xsl:call-template name="XYZ">
                 <xsl:with-param name="nodeset"
select="$nodeset[position() &gt; 1]" />
                 <xsl:with-param name="n" select="$n + 1" />
               </xsl:call-template>
           </xsl:when>
           <xsl:otherwise>
               <xsl:value-of select="$n" />
           </xsl:otherwise>
       </xsl:choose>

Hello List,

I have to count a number of nodes. Each node that is to be counted has an
attribute 'count-me="yes"' (this is a example :)). But as soon there is a
node which does'nt have such an attribute, or has a attribute
'count-me="false"' this and all following nodes are not to be counted. The
result value is dependent on the number of the node that is in the focus.

Example:
<theExampleXMLTree>
       <Node count-me="yes"/>
       <Node count-me="yes"/>
       <Node count-me="yes"/>
       <Node/>
       <Node count-me="no"/>
       <Node count-me="yes"/>
</theExampleXMLTree>

The value wanted is e.g. 2 when processing the first node.

...

This is how I've tried it so far. The problem here is, that when processing
the first Node I always get the value of 4 (what is quite logical to me).

<xsl:template natch="Node" mode="counting_example">
 <xsl:variable name="number" select="following-sibling::*[@count-me =
'yes')]"/>
</xsl:template>

I also tried:
 <xsl:variable name="number" select="following-sibling::*[position()
+1][@count-me = 'yes')]"/>

But that just counts the next node if it has the matching attribute.

Let me show what I actually want at the following tabel (using the XML shown
above):
NodeNr.|Value
1|2
2|1
3|0
4|0
5|1
6|0

Is this possible? and how?

With best regards,
Jan
