[jdom-interest] Problems by sorting the list (JDOM beginner)

[Julien GROUTEAU]

One thing I found useful, while sorting list of childrens, is to detach them
prior to any 'processing' on them.

So I would say :

List ch = root.getChildren;
Iterator it = ch.iterator ();
while (it.hasNext ()) {
	Element element = (Element) it.next ();
	element.detach ();
}
Collections.sort (ch , mycomp);

Hope this helps.

Julien

Hi!

My problem is, I can't sort the List!
I use:
List ch = root.getChildren;
Collections.sort( ch , mycomp );

I wrote a comparator, what works.
But I got an exception:
org.jdom.IllegalAddException: The element already has an existing parent
"root"

I tried to search in the archive, but I couldn't find any solutions!


Thanks, Galuc
