The code below will, if put in the HEAD of a page, move all LI-items that contains a <del>-tag to the bottom of the list. Handy for TODo-lists.

	<script type="text/javascript">
		function organizeList(list) {
		      var listItems = list.getElementsByTagName("LI");
		      var len = listItems.length;
		      for (var i = 0;i<len;i++) {
		            if (listItems[i].getElementsByTagName("DEL").length > 0) {
		                list.appendChild(listItems[i]);
		                i--;
		                len--;
		            }
		      }
		  }
	  window.onload = function() {
	      var lists = document.getElementsByTagName("UL");
	      for (var i = 0;i<lists.length;i++) {
	            organizeList(lists[i]);
	      }
	  }
	</script>
