Default help needed in DOM

Hi, i am writing a simple parser using JavaScript that parses a simple HTML. In one part of the code i retireive all children of a node, in my body (html) i have only three elements <h1><div><input>, however my code output some #text tags along with them, i tried outputting the content and it says undefined??? really puzzled here, i have removed all white spaces still the same...

CODE:------------------------------------------------
HTML Code:
<html>
<head>
<script>
    	function outPutNodeName(child1)
	{
		ndName = child1.nodeName.toLowerCase();
		if(ndName == "#text")
		{
		document.write("node name = " + ndName + " and text = " + ndName.nodeValue + "</br>");
		}
		else
		{
		document.write("node name = " + ndName + "</br>");
		}
	}
	
	function countChildren(node1)           // counts children of the passed tag
	{
		var chren = node1.childNodes; // Now get all children of n
        for(var i=0; i < chren.length; i++)
		{
			outPutNodeName(chren[i]);
		}
		document.write("No of children = " + i + "</br>");
	}
		
function testTags(node)            
	{ 
        var child = node.firstChild; 	// the root of is the document then come HTML tag
		var type = child.nodeType;
		countChildren(document.body);  
}
</script>
</head>


<body>
<h1 id ="foo">hello</h1>
<div>hello</div>
<input type="button" value="Add Child Element" onclick="testTags(document)">
</body>
</html>
:------------------------------------------------

OutPut:
node name = #text and text = undefined <----------what is this element
node name = h1
node name = #text and text = undefined
node name = div
node name = #text and text = undefined
node name = input
node name = #text and text = undefined
No of children = 7
