Here's one approach; the 'thisChild.nodeType' line is to ignore
attribute (type 2) and text (type 3) nodes.

<script type="text/javascript">
                    /* Tested in Moz 1.4 and Opera 7.11 (Win) */
function init()
{
	var parent1 = document.getElementById("parentDiv1");
	var thisChild = parent1.firstChild;
	while ( thisChild != parent1.lastChild )
	{
		if ( thisChild.nodeType == 1 )
		{
			alert(thisChild.id);
		}
		thisChild = thisChild.nextSibling;
	}
}

window.onload=init;
</script>

HTH!
