我正在为我正在开发的 android 应用程序使用 SAX 解析器，我很难尝试保存 Project 的名称标签以免被覆盖。这里的问题是我在项目中的名称标签被许可证中的名称标签覆盖，因为标签是相同的。其余的被很好地解析了。此外，这个 xml 是通过将 GET 请求传递给 API 来生成的，所以我无法编辑它。有没有办法可以省略许可证字段中的名称标签，或者尝试了解我在文档中的位置，这是一个问题，因为 SAX 甚至是驱动的。另外，我意识到使用 DOM 可以很容易地完成此任务，但我现在已经走得太远了，无法切换到 DOM。我附上了我的 XML 处理代码片段和我试图解析的 xml 文件。

谢谢

您可以通过简单的方式解决您的问题。

  1. 在您的类处理程序中创建一些标志。

    private boolean inProject = false;
private boolean inLicense = false;

  2. 像我在下面展示的那样控制这些标志。

       @Override
   public void startElement (String namespaceURI, String localName, String qName, Attributes attributes) throws SAXException 
   {
      if (localName.equalsIgnoreCase("project")) {
           this.inProject = true;
      }
      else if (localName.equalsIgnoreCase("license")) {
           this.inLicense = true;
      }
   }

   @Override
   public void endElement (String namespaceURI, String localName, String qName) throws SAXException
   {       
       if (localName.equalsIgnoreCase("name") {
           if(inProject) { 
              //Set your project name here.
              this.inProject = false;
           }
           else if (inLicense) {
              //Set your lencense name here.
              this.inLicense = false;
           }
       }
    }

让我知道它是否有效。
