[jdom-interest] Is it possible in JDOM...?

[Benjamin Kopic]

You need to detach the element from its original parent.
 
//apply being the root element of our original tree
 
List children = apply.getChildren();
ListIterator iterator = children.listIterator(1);

Element root = new Element("root");
Element newElem = new Element("eq");
root = root.addContent(newElem);
for(int i=0; i<2; i++) {
  Element nextElement = (Element) iterator.next();
  root = root.addContent(nextElement.detach());
}
