我的问题是，提取该数据的最佳方法是什么？是否应该有更好的方法来输出 XML 数据？

Answer 1

一个非常好的工具是 Simple 。您要做的就是编写一个简单的对象来序列化数据。例如。

@Default
private class Structure {

   @Path("info")
   private String ip;

   @Path("host")
   private String host;

   @Path("path")
   private String country;

   @Path("path")
   private String cimg;

   @ElementList
   private List<Entry> searches;

   @Root
   private static class Entry {

      @Attribute
      private String link;

      @Attribute 
      private String title;
   }
}

然后您所要做的就是将数据读入对象实例。

Serializer serializer = new Persister();
Structure structure = serializer.read(Structure.class, inputStream);

该框架几乎适用于所有 Android 版本。欲了解更多信息，请访问 Tutorial .
