Try this: DocumentFactory documentFactory = new DocumentFactory(); Element el = documentFactory.createElement(QName.get("OAI-PMH", "", "http://www.openarchives.org/OAI/2.0/")); el.addAttribute( QName.get("schemaLocation", "xsi", "http://www.w3.org/2001/XMLSchema-instance"), "http://www.openarchives.org/OAI/2.0/ http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd"); Document document = documentFactory.createDocument(el);
System.out.println(document.asXML()); Or you can use Namespace object instead of three-param QName.get() method, or you can use "qualified name" and namespace-to-prefix map of document factory.
