假设您要坚持使用标准API …
您可以使用DOMImplementationLS：
document document = node.getOwnerdocument();DOMImplementationLS domImplLS = (DOMImplementationLS) document .getImplementation();LSSerializer serializer = domImplLS.createLSSerializer();String str = serializer.writeToString(node);
如果
<？xml version =“ 1.0” encoding=“UTF-16”？>声明使您感到困扰，则可以使用转换器：
TransformerFactory transFactory = TransformerFactory.newInstance();Transformer transformer = transFactory.newTransformer();StringWriter buffer = new StringWriter();transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");transformer.transform(new DOMSource(node), new StreamResult(buffer));String str = buffer.toString();
