Robert H. Pollack commented on XMLBEANS-100:
--------------------------------------------

What works for me as a workaround is to copy the DOM tree created by XMLBeans into a \
Document created by the JDK's DocumentBuilder. In other words, suppose we have a \
Document that has been obtained by something like this:

   Document doc1 = (Document) myXMLObject.newDomNode();

Create a DocumentBuilder in the usual way and use it to build a new Document:

   DocumentBuilder builder = \
DocumentBuilderFactory.newInstance().newDocumentBuilder();  Document doc2 = \
builder.newDocument();

(you'll need exception handlers not shown here). Then import the first Document into \
the second:

   Element newRoot = (Element) doc2.importNode (doc1.getDocumentElement(), true);
   doc2.appendChild (newRoot);

Now do your work--transformations or whatever--with doc2, which will be a DOM level 3 \
Document.

As I say, this is working fine for me; the JVM has no problem handling two different \
DOM implementations, a level 2 implementation from XMLBeans and a level 3 \
implementation from the JDK. And the JDK's implementation seems to have no trouble \
importing nodes from XMLBeans' implementation. Admittedly, this would not scale to \
large trees; I have no workaround to suggest when the tree is so large that copying \
it is expensive.

If, afterward, you need to turn this back into an XmlObject, it should be possible to \
do this by using XmlObject.Factory.parse (doc2), although I haven't tested this since \
my application doesn't need it.
