java - ElementNSImpl 到字符串

Question

我有一个调用网络服务的客户端，我正在返回一个 ElementNSImpl 对象。 是否可以将此对象转换为字符串？

对于 org.w3c.dom.Document 对象，我使用了这样的代码:

protected static String documentToString(final Document doc) {
        // outputs a DOM structure to plain String

        try {
            StringWriter sw = new StringWriter();
            TransformerFactory tf = TransformerFactory.newInstance();
            Transformer transformer = tf.newTransformer();
            transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
            transformer.setOutputProperty(OutputKeys.METHOD, "xml");
            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");

            transformer.transform(new DOMSource(doc), new StreamResult(sw));
            return sw.toString();
        } catch (Exception ex) {
            throw new RuntimeException("Error converting to String", ex);
        }
    }

您可以从 ElementNSImpl 对象中获取 org.w3c.dom.Document。 在这里:

 ElementNSImpl eleNsImplObject =somehowGetThatElement();
 org.w3c.dom.Document document = eleNsImplObject.getOwnerDocument();

希望这对您有所帮助。
