java的Document对象如何转字符串？

java的Document对象如何转字符串？

解决方法：

下面的document就是org.w3c.dom.Document的对象

       TransformerFactory tf = TransformerFactory.newInstance();

       Transformer transformer = tf.newTransformer();

       DOMSource source = new DOMSource(document);

       transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");

       transformer.setOutputProperty(OutputKeys.INDENT, "yes");

       StringWriter writer = new StringWriter();

       StreamResult result = new StreamResult(writer);

       transformer.transform(source, result);

       String output = writer.getBuffer().toString();
