[jdom-interest] Moving Children

[Kevin Baynes]

Jason-

How do I clone the List?

Do you mean to do this?:

// Assume creation of two Elements usersA and usersB, each with children

Element clone = (Element)usersA.clone();

java.util.List listA = clone.getChildren();
java.util.List listB = usersB.getChildren();

listB.addAll( listA  );


Did I misunderstand?

Thanks!

Kevin
