Question

阅读java org.w3c.dom.ls的文档它似乎只能将元素序列化为带有java本机字符串编码的字符串UTF-16。但是，我需要创建一个UTF-8字符串，转义或不存在，我知道它仍然是一个UTF-16字符串。任何人都有想法绕过这个？我需要将字符串传递给将使用String的生成的WS客户端，然后它应该是UTF-8。

我用来创建字符串的代码：

DOMImplementationRegistry domImplementationRegistry = DOMImplementationRegistry.
DOMImplementationLS domImplementationLS = (DOMImplementationLS) REGISTRY.getDOMImplementation("LS");
LSSerializer writer = domImplementationLS.createLSSerializer();
String result = writer.writeToString(element);

Answer 1

您仍然可以使用DOMImplementationLS：

DOMImplementationRegistry domImplementationRegistry = DOMImplementationRegistry.
DOMImplementationLS domImplementationLS = (DOMImplementationLS)REGISTRY.getDOMImplementation("LS");
LSOutput lsOutput =  domImplementationLS.createLSOutput();
lsOutput.setEncoding("UTF-8");
Writer stringWriter = new StringWriter();
lsOutput.setCharacterStream(stringWriter);
lsSerializer.write(doc, lsOutput);     
String result = stringWriter.toString();

Answer 2

我发现将DOM序列化为String的最灵活方式是使用javax.xml.transform API：

    Node node = ...
    StringWriter output = new StringWriter();

    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.transform(new DOMSource(node), new StreamResult(output));

    String xml = output.toString();

它不是特别优雅，但它可以让你更好地控制输出编码。

DOMImplementationLS在Java中以UTF-8序列化为String
