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.
