[dom4j-user] BackedList sorts

[Mike Evans]

Hi All,
I'm using dom4j1.6.
I need to sort child elements returned by the the elements() method 
using an external Comparator.
However this returns a BackedList.  When sorted its set() method calls 
addNode() and removeNode() which throw Exceptions as the node's parent 
is already defined.
Currently I get around it like this:

public List getOrderedChildren( Element parent ) {
  List backedList = parent.elements();
  if ( !backedList.isEmpty() ) {
    List children = new ArrayList( backedList );
    Collections.sort( children, myComparator );
    return children;
  }
  return Collections.EMPTY_LIST;
}
Has anyone any better ideas that do not involve the instantiation of an 
additional ArrayList every time?

Many thanks,
Mike E.
