You need to use the node-set extension function.

Something like following:

<xsl:stylesheet version="1.0"
     
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
      xmlns:msxsl="urn:schemas-microsoft-com:xslt">

<xsl:template match="/records">
 <xsl:variable name="rtf">
 <records>
   <xsl:for-each select="record[parentkeynum = 0]">
     <record>
       <xsl:variable name="key1" select="keynum" />
       <xsl:copy-of select="*" />
       <xsl:for-each select="../record[parentkeynum
=
$key1]">
         <record>
           <xsl:variable name="key2" select="keynum"
/>
           <xsl:copy-of select="*" />
           <xsl:for-each
select="../record[parentkeynum = $key2]">
             <record>
               <xsl:copy-of select="*" />
             </record>
           </xsl:for-each>
         </record>
       </xsl:for-each>
     </record>
   </xsl:for-each>
 </records>
</xsl:variable>

<xsl:call-template name="dve">
  <xsl:with-param name="nodeset"
select="msxsl:node-set($rtf)" />
</xsl:call-template>

</xsl:template>

<xsl:template name="dve">
 <xsl:param name="nodeset" />
   <xsl:for-each select="$nodeset//records/record">
     <xsl:call-template name="SubMenu">
       <xsl:with-param
name="strCSS">ParentIsVisible</xsl:with-param>
     </xsl:call-template>
   </xsl:for-each>
</xsl:template>

The rest of the code would probably remain same..

Thanks Mukul,
The levels are only 3 yes. But how to use

heirarchy

XML made by template. This is what I trying:

<?xml version="1.0" ?>
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>

<xsl:template match="/records">
 <records>
   <xsl:for-each select="record[parentkeynum =

0]">

     <record>
       <xsl:variable name="key1" select="keynum"

/>

       <xsl:copy-of select="*" />
       <xsl:for-each

select="../record[parentkeynum =

$key1]">
         <record>
           <xsl:variable name="key2"

select="keynum"

/>
           <xsl:copy-of select="*" />
           <xsl:for-each
select="../record[parentkeynum = $key2]">
             <record>
               <xsl:copy-of select="*" />
             </record>
           </xsl:for-each>
         </record>
       </xsl:for-each>
     </record>
   </xsl:for-each>
 </records>
<xsl:call-template name="dve">
</xsl:call-template>

</xsl:template>

<xsl:template name="dve" match="/">
 <xsl:for-each select="//records/record">
 <xsl:call-template name="SubMenu">
  <xsl:with-param name="strCSS">Parent
IsVisible</xsl:with-param>
 </xsl:call-template>
 </xsl:for-each>
</xsl:template>

<xsl:template name="SubMenu">
 <xsl:param name="strCSS" />



 <div class="{$strCSS}">
 <xsl:choose>
  <xsl:when test="count(record) > 0">
   <!-- Element has children, it can be expanded

-->

   <input type="hidden" id="hidIsExpanded"

value="0"

/>
   <label id="lblExpand" class="Expander"
onclick="ExpanderClicked()">+</label>
  </xsl:when>
  <xsl:otherwise>
   <label class="Expander"></label>
  </xsl:otherwise>
 </xsl:choose>

 <a><xsl:value-of select="keyname" /></a>
 <xsl:for-each select="record">
  <xsl:call-template name="SubMenu">
   <xsl:with-param
name="strCSS">NotVisible</xsl:with-param>
  </xsl:call-template>
 </xsl:for-each>
 </div>
</xsl:template>

</xsl:stylesheet>



and than I use this ASP

<%@ Language=VBScript %>
<% option explicit %>
<HTML>
<HEAD>
<link type="text/css" rel="stylesheet"
href="alerts.css" />
</HEAD>
<BODY>
<b>Alerts</b>
<%
       dim xmlMenu
       dim xslMenu

       'Get the source XML
       set xmlMenu =

server.CreateObject("Microsoft.XMLDOM")

       xmlMenu.async = false
       xmlMenu.load server.MapPath("probe.xml")

       'Get the XSLT to transform the XML
       set xslMenu =

server.CreateObject("Microsoft.XMLDOM")

       xslMenu.async = false
       xslMenu.load server.MapPath("probe.xsl")

       'Transform the source XML using XSLT
       Response.Write

xmlMenu.transformNode(xslMenu)


       set xmlMenu = nothing
       set xslMenu = nothing
%>

<script language="jscript">
function ExpanderClicked()
{
       //Get the element that was clicked
       var ctlExpander = event.srcElement;
       var ctlSelectedEntry =

       //Get all the DIV elements that are direct
descendants
       var colChild =

ctlSelectedEntry.children.tags("DIV");

       if(colChild.length > 0)
       {
               var strCSS;
               //Get the hidden element that

not entry is expanded
               var ctlHidden =
