[dom4j-user] Bug in remove functions?

[Christian Holmqvist, IT, Posten]

(I posted this msg för about a month ago but did not get any feed back, henc repost...)   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
