Nope, that won't work, you can't construct a new loop in every call of
the method.
Try passing the list in as a parameter and using the NodeList, like
this:
public void getChildren( Element element, List elements ) {
elements.add( element );
NodeList list = element.getChildNodes();
for( int i = 0; i < list.getLength(); i++ ) {
if( list.item( i ).getNodeType() == Node.ELEMENT_NODE ) {
getChildren( ( Element )list.item( i ), elements );
}
}
}

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) {

* return elements;
