First, get rid of the global, like so:

*  public List getChildren(Element element) {
> 
*     List elements = new ArrayList();
>     elements.add(element);
> 
>     Node child;
>     Node next = (Node) element.getFirstChild();
>     while ((child = next) != null) {
>         next = child.getNextSibling();
>             if (child.getNodeType() == Node.ELEMENT_NODE) {
>                 getChildren((Element) child);
>             }
>         }
*     return elements;
> }

Next, get rid of all the carriage returns. 

That knocks it down to about one line of code.  I like my Chianti very dry,
thank you.
