Like this:

Element e = paramxmlDoc.getRootElement();
paramxmlDoc.setRootElement(null); // break connection between doc and element
rootXMLDoc.getRootElement().addChild(e); // Insert node in other document

Note: This is from memory, so the actual method calls can be slightly different but you get the idea.
