java - 将xml节点的所有内容作为字符串

Question

我正在使用此代码来解析xml

    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(data));
    Document doc = db.parse(is);

现在我想从xml节点获取所有内容.喜欢这个xml

<?xml version='1.0'?>
<type>
  <human>                     
    <Name>John Smith</Name>              
    <Address>1/3A South Garden</Address>    
  </human>
</type>

所以如果想要获得所有内容的<human>文本.

<Name>John Smith</Name>
<Address>1/3A South Garden</Address>

我怎么才能得到它 ？

private String nodeToString(Node node) {
  StringWriter sw = new StringWriter();
  try {
    Transformer t = TransformerFactory.newInstance().newTransformer();
    t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    t.transform(new DOMSource(node), new StreamResult(sw));
  } catch (TransformerException te) {
    System.out.println("nodeToString Transformer Exception");
  }
  return sw.toString();
}
