如何用java将org.w3c.dom.Element输出到字符串格式

 

方法一
DOMImplementationLS lsImpl = (DOMImplementationLS)node.getOwnerDocument().getImplementation().getFeature("LS", "3.0");
LSSerializer serializer = lsImpl.createLSSerializer();
serializer.getDomConfig().setParameter("xml-declaration", false); //by default its true, so set it to false to get String without xml-declaration
String str = serializer.writeToString(node);

方法二

Document document = node.getOwnerDocument();
DOMImplementationLS domImplLS = (DOMImplementationLS) document
    .getImplementation();
LSSerializer serializer = domImplLS.createLSSerializer();
String str = serializer.writeToString(node);



如果不要<?xml version="1.0" encoding="UTF-16"?>声明：

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();
