Walking the DOM Recursively

Recursive DOM Example

function walkTheDOM(node, F)
		{
			F(node);
			node = node.firstChild;
			while (node)
			{
				walkTheDom(node, F);
				node = node.nextSibling; //Changes state here, destroying node
			}
		}
		

walkTheDOM(document.getElementById("theBody"),
			function(node)
			{
				alert(node.nodeName + "," + node.nodeValue);
			});
