[xsl] count Nodes with attributes until... (XSLT 1.0)

2006-06-28 02:09:23
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::*[(_at_)count-me =
'yes')]"/>
</xsl:template>

I also tried:
  <xsl:variable name="number" select="following-sibling::*[position()
+1][(_at_)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
