Question

I have an xml like

<MainNode>
 <Data SubjectID="19233">
  <SubNode CS="100,1" >
   <AB V="PSDF"/>
  </SubNode>
 </Data>
 <Data SubjectID="19234">
  <SubNode  CS="111,1">
   <AB V="PSDF" />
  </SubNode>
 </Data>
</MainNode>

When i try to sum the value of attribute “@CS” i am getting “NaN” as result. Can anyone help me to solve this issue.

Thanks in advance

I think this is overcomplicated, but you could try:

<xsl:template name="sum_helper">
  <xsl:param name="current" select="0" />
  <xsl:param name="rest" /> 
  <xsl:choose>
    <xsl:when test="count($rest) &gt; 0">
      <xsl:call-template name="sum_helper">
        <xsl:with-param name="current"
                        select="$current + translate($rest[1],',','.')" />
        <xsl:with-param name="rest" select="$rest[position()&gt;1]" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="$current" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

   ...
   <xsl:call-template name="sum_helper">
     <xsl:with-param name="rest" select="//SubNode/@CS" />
   </xsl:call-template>
   ...
