You could use XPath expressions to determine when to prune the tree while
parsing is occurring.
SAXReader reader = new SAXReader();
reader.setDefaultHandler(
new ElementHandler() {
public void onStart(ElementPath path) {
}
public void onEnd(ElementPath path) {
Element element = path.getCurrent();
// process this element if its one I need.
// do I need to prune this element?
if (someXPath.matches(element)) {
element.detach();
}
}
}
);
