Hi,
thanks for all your helpful comments.
After thinking about your hints and tips, I think, I've found the answer to
my problem:
I used the wrong methods to add my attributes (and maybe even my elements
but that didn't seem to make a difference).
old: element.addAttribute("xml:lang", "en");
new: QName qname = DocumentFactory.getInstance().createQName("lang", "xml",
"http://www.w3.org/XML/1998/namespace";);
element.addAttribute(qname , "en");
Now, my XPath queries deliver the desired elements (so far ;-)
