Java 当我从xml节点获取数据时，得到的是空数据

当我尝试从XML节点读取值时，接收到的是“null”值

结构示例：

党卫军
ssss

结果：o/p[用户：空][密码：空]

这是我的代码：

public class stres() {  
   public static void main(String[] args) throws SQLException, ParserConfigurationException, SAXException, IOException {
      try {
         String resulturl ="my url";

         DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
         DocumentBuilder db = dbf.newDocumentBuilder();

         Document doc = db.parse(resulturl);

         NodeList documentt = doc.getElementsByTagName("document");     

         for (int i = 0; i < documentt.getLength(); i++) {
            Element data = (Element) documentt.item(0);
            Node user = data.getElementsByTagName("user").item(0);
            Node password = data.getElementsByTagName("password").item(0);

         }
      }
      catch(Exception e) {
         e.printStackTrace();
      }
   }
}

公共类stres（）{
公共静态void main（字符串[]args）抛出SQLException、ParserConfiguration异常、SAXException、IOException{
试一试{
String resultur=“我的url”；
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance（）；
DocumentBuilder db=dbf.newDocumentBuilder（）；
Document doc=db.parse（resultur）；
NodeList documentt=doc.getElementsByTagName（“文档”）；
对于（int i=0；i

请设置该代码的格式。这是我的xml代码ss SSS o/p[user:null][password:null]，首先确保已加载xml。您可以通过System.out.println（doc.getDocumentElement（）.getTextContent（））；。。我试过这种方法，shubham得到的o/p是这样的o/p:N17 ssivFspre univv>pre univv>rgs.NodeList documentt=doc.getElementsByTagName（“文档”）；System.out.println（“documenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt；o/p:com.sun.org.apache.xerces.internal.dom。DeepNodeListImpl@243e0b62
