如何在java中解析soap字符串

我已经编写了下面的代码来解析java中的字符串，但它并没有打印出一条空白消息

如何从SOAP消息中获取特定部分并获取它们的值？ 我想获取请求中的错误和消息

String xml = "<?xml version='1.0' encoding='UTF-8'?>"
             + "<S:Envelope xmlns:S=\"http://schemas.xmlsoap.org/soap/envelope/\">"
             + "<S:Body>"
             + "<ns2:processResponse xmlns:ns2=\"http://ws.xxxxx.com/\">"
             + "<response><direction>response</direction>"
             + "<reference>09FG10021008111306320</reference>"
             + "<amount>0.0</amount>"
             + "<totalFailed>0</totalFailed>"
             + "<totalSuccess>0</totalSuccess>"
             + "<error>1</error>"
             + "<message>Invalid</message>"
             + "<otherReference>6360e28990c743a3b3234</otherReference>"
             + "<action>FT</action>"
             + "<openingBalance>0.0</openingBalance>"
             + "<closingBalance>0.0</closingBalance>"
             + "</response>"
             + "</ns2:processResponse>"
             + "</S:Body>"
             + "</S:Envelope>\n";

         SAXBuilder builder = new SAXBuilder();
            Reader in = new StringReader(xml);
            Document doc = null;
            Element root = null;
            Element meta = null;
            Element error = null;
            Element status_message = null;
            String status_code= "";
            String message = "";
            try
            {
             doc = builder.build(in);
             root = doc.getRootElement();
             meta = root.getChild("processResponse").getChild("response");
             error = meta.getChild("error");
             status_message = meta.getChild("message");
             status_code = error.getText();
             message = status_message.getText();

            }catch (Exception e)
             {
             // do what you want
             }
            System.out.println("status_code: " + status_code + "\nmessage: " + message);

String xml=“”

正在生成的响应是 状态代码：

消息：

将xml转换为json，然后您可以用它做任何事情。请记住，创建一个适当的模型类来通过json映射数据

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20171018</version>
</dependency>

在提取xml中的元素时，代码中出现了一些错误。您可以使用此代码并检查

        String xml = "<?xml version='1.0' encoding='UTF-8'?>"
