The safer method would be as in my previous example: var oldLast = element.lastChild; //you don't care what this is, just stored for later reference new Insertion.Bottom(element,content); var newEl = Element.next(oldLast); //gets the div you inserted If the content you are inserting has multiple siblings, then the above code would work to get the first element. TO get subsequent elements just keep using Element.next: //do something with the newEl from above (first element inserted) while(newEl = Element.next(newEl)){ //do something with each additional sibling element inserted } One caveat, if element is completely empty then storing oldLast will not work because there is no lastChild. Could be solved like so: if(!element.lastChild) element.appendChild(document.createTextNode()); var oldLast = element.lastChild; //now oldLast is guaranteed to exist .... Or, if inserting one extraneous empty text node is something you have problems with there are other solutions which I'll leave up to those who care. <-(my disclaimer in case someone decides to pipe in their objections) Colin Daniel Eben Elmore wrote: > I'm primarily using Insertion.Bottom and don't see how to use the traversal > methods because I don't know when I've reached the last element.
