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.
