[jdom-interest] Merging JDOM documents

[Rosén Håkan]

Hi, thanks for answering !
My problem remains, cloning effects the origin document.
I'd rather like to make a copy of my second document,
is there a nice way to make a deep-copy of an Element ?
regards

Hi,

what did you expect when you detached the root
element from the document? 

You must either clone the element

   inReport.getRootElement().getChild("employee").addContent
                         (Element)(rules.getRootElement().clone());

or, if concurrency is not an issue, save a reference
to the detached element and after finishing
the process, detach it from the first document and set
it back as root element in the second.
