Re: counting specific nodes

Here is another solution --

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan">
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:variable name="startpos">1</xsl:variable>
	
<xsl:template match="/vs">
   <xsl:variable name="dots">
      <xsl:for-each select="ve">
	<xsl:variable name="val"
select="substring(@pos,1,1)"/>
	<xsl:if test="($val = $startpos) or ($val &gt;
$startpos)">
	    <xsl:call-template name="countdots">	     
<xsl:with-param name="stringparam" select="@pos"/>
	      <xsl:with-param name="noofdots" select="0"/>
	    </xsl:call-template>
	</xsl:if>
     </xsl:for-each>
   </xsl:variable>
		
   Answer - <xsl:value-of
select="count(xalan:nodeset($dots)/a)" />
</xsl:template>
	
<xsl:template name="countdots">
  <xsl:param name="stringparam"/>
  <xsl:param name="noofdots"/>
  
  <xsl:variable name="sbst"
select="substring-after($stringparam, '.')"/>
  <xsl:if test="$sbst != '' ">
     <xsl:call-template name="countdots">
	<xsl:with-param name="stringparam" select="$sbst"/>
	<xsl:with-param name="noofdots" select="$noofdots +
1"/>
     </xsl:call-template>
  </xsl:if>
  <xsl:if test="$sbst = '' ">
     <xsl:if test="$noofdots = 3">
	<a/>
     </xsl:if>
  </xsl:if>
</xsl:template>

</xsl:stylesheet>

At the begining of XSL, a varibale is declared to
mention the starting position; <xsl:variable
name="startpos">1</xsl:variable>

The XSL uses recursion to find the count of the
desired nodes. The above XSL creates a tag <a/> each
time it encounters a node in original XML having 3
dots (whose position is, on or after the "startpos"
value node). A variable "dots" ( declared as --
<xsl:variable name="dots"> )holds these <a/> tags
(which is a RTF -- result tree fragment). 

I convert the RTF into a nodeset, and calculate the
count of <a/> tags, *which is the answer*.
