Get Children

How would I get the first level children and not get the grandchildren as well

for instance

<div id="topLevel">
  <div>
    <div>
    </div>
  </div>
  <div>
  </div>
<div>

so, if I am starting from the div with the ID of "topLevel" how do I get the child div's one level down and not the grandchild div. I've tried getElementByTagName and this returns all three div's when I only want to get 2 of them.

try this
 <%
	Set objXML = Server.CreateObject("Microsoft.XMLDOM")
    sXMLFile = Server.MapPath("\") & "\xmldoc.xml"
    objXML.load(sXMLFile)
	Set oNodes = objXML.selectNodes("//div/*")
    For Each oChild In oNodes
        Response.Write oChild.tagname & "<BR>"
	Next
%>

You've lost me.

What does VBScript have to do with getting elements in JavaScript.

The purpose of this is so that I can set style properties dynamically.

Use the childNodes collection, but remember to check if each node is an element node by checking if the node's nodeType property is set to 1 or not.

Not one to sit around and wait, I tried childNodes last night. The problem with this is that if there is some other type of element in there that is returned as well.

For instance if you have:

<div>
  <div></div>
  <span><span>
</div>

Both the div and the span are returned as element type 1. It seems no matter which route I go, I'm getting more information than I want.

Is there any way to tell what type of element each of the childNodes really is? Is it a div, span, ul. Seems to me there should be some way to get only the first level children of a specific element type.

Sure. Use the nodeName property. (It's best to use toLowerCase() on it before comparing it to a string.)

here is a the sample script which will read only divs in the documents..
<div>
	<div>div1</div
	<span>span1</span>
</div>
<SCRIPT>
 
	var divs = document.getElementsByTagName( 'DIV' );
    for ( var i = 0; i < divs.length; i++ ) 
	{
        alert(divs[i].innerText);
    }
</SCRIPT>

I decided to limit nested divs. So each div can only contain one child div. This allows me to use the getElementsByTagName and then take the first one which is the immediate child.

Not the best solution and not quite what I was looking for, but it will work for the intended purpose.
