[jdom-interest] parsing jdom

[Chris B.]

List result = new ArrayList();
doit(doc.getRootElement(), "z", result);

void doit(Element el, String name, List result) {
    if (el.getName().equals(name)) {
       result.add(el.getParent());
    }
    Iterator it = el.getChildren().iterator();
    while (it.hasNext()) {
       doit((Element)it.next(), name, result);
    }
}
