我正在尝试

 public static void main(String[] args) {
       try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = null;
        try {
            docBuilder = factory.newDocumentBuilder();
        } catch (ParserConfigurationException ex) {
            Logger.getLogger(DomeParser.class.getName()).log(Level.SEVERE, null,  ex);           
        }

       Document doc = docBuilder.parse (new File("test.xml"));

        NodeList list = doc.getElementsByTagName("*");

         for (int i = 0; i < list.getLength(); i++) {

            Element element = (Element) list.item(i);
            String nodeName = element.getNodeName();

             if (nodeName.equals("GMSport")) {
                 System.out.print(nodeName+"|");

            }

             else if (nodeName.equals("Category")) {
                System.out.print(nodeName+"|");

            }
            else if (nodeName.equals("Tournament")) {
                     System.out.print(nodeName+"|");
            }

        }

    } catch (SAXException ex) {
        Logger.getLogger(DomeParser.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(DomeParser.class.getName()).log(Level.SEVERE, null, ex);
    }
 }

Answer 1

1. 创建适当的领域类，例如体育、类别、锦标赛等。
2. 从 XML 创建域类(您可以像当前一样使用 JAXB 或原始 DOM)
3. 一旦构建了域类，您就可以使用它们以任何您想要的方式打印它。

在您当前的代码中，您将解析和报告/打印逻辑混合到不可扩展的代码中。
