Re: [dom4j-user] Bug in remove functions?

I guess this is a bug that needs fixing. I suppose setRootElement() should only remove any existing Element instances but keep any PI or comments. I guess the Element should be appended to the end of the Document's content() List.

Hi
 
I got a document that look like this:
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <author name="James" location="UK">James Strachan</author>
  <author name="Bob" location="US">Bob McWhirter</author>
</root>
<?kalle kalle?>
 
What I want to do is to move the Process instruction to be located right after the xml tag (<?xml....?>).
I can do this with these lines:
 
    Node el = document.getRootElement().detach();
    document.add(el);
And the result is like this:
<?xml version="1.0" encoding="UTF-8"?>
<?kalle kalle?>
 
<root>
  <author name="James" location="UK">James Strachan</author>
  <author name="Bob" location="US">Bob McWhirter</author>
</root>
 
And this is correct. BUT if I instead do:
    Node el = document.getRootElement().detach();
    document.setRootElement((Element)el);
The result looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <author name="James" location="UK">James Strachan</author>
  <author name="Bob" location="US">Bob McWhirter</author>
</root>
 
As you can see the Process instruction (<?kalle kalle?>) is removed and it should not be since I only detached the rootelement and only set a new root element...
 
Is this a bug in dom4j or have I missed something in the implementation?
 
Thankfull for any input!
 
Cheers Christian Holmqvist
