我的问题是，提取数据的最佳方法是什么？是否有更好的方法来提取XML数据

Answer 1

一个很好的工具是Simple。您需要做的一件事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;
   }
}

然后你需要做的就是把数据读入一个对象实例

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

这个框架适用于几乎所有的Android版本。欲了解更多信息，请点击Tutorial
