 <xsl:template match="ArrayOfLinkEntity" name="bindLink">
  <ul>
   <xsl:for-each select="LinkEntity[ParentLinkId=0]">
     <li>
       <xsl:variable name="linkId" select="LinkId"/>
       <xsl:variable name="child" select="count(/ArrayOfLinkEntity/LinkEntity[ParentLinkId=$linkId])"/>
       <xsl:value-of select="$child"/>
       <xsl:choose>
         <xsl:when test="($child &gt; 0)">
           <a href="#"  data-flexmenu="flexmenu1" onclick="javascript:setPageLinkId({$linkId});">
             <xsl:value-of select="LinkTitle"/>
             <img src="../images/down.gif" border="0"/>
           </a>
         </xsl:when>

         <xsl:otherwise >
           <a href="#" onclick="javascript:setPageLinkId({$linkId});">

If by "children" you mean a LinkEntity with ParentLinkId child that is equal to the LinkId of the current node, the result you get is correct.

The only LinkEntity has an LinkId 1, but there are no LinkEntity elements in the provided XML document whose ParentLinkId is 1.

You need to show a complete (but the shortest possible) XML document on which your code exhibits this issue. Without being able to repro the problem, no one can give you a logical advice.

From your following code:

<xsl:variable name="linkId" select="LinkId"/>
      <xsl:variable name="child" select="count(/ArrayOfLinkEntity/LinkEntity[ParentLinkId=$linkId])"/>

This occurs within a for-each loop where the only nodes being looped over are LinkEntity's with ParentLinkId = 0. But from your source XML, the value of LinkId = 1, and in your variable assignment for $child, you are selecting on LinkEntity's with ParentLinkId = 1, which don't exist in your source XML data.

If I misunderstood something please let me know, but from what I can see that may be the problem.
