//        xstream.useAttributeFor(Province.class, "name");

//        去除集合属性对应元素,因为Pronvice类有一个cities成员，所以生成了<cities>元素，但这个元素对XML文档而言没有什么意义，所以我们希望把它去除！

//        xstream.addImplicitCollection(Province.class, "cities");

//        让类的成员不生成对应XML元素,我们都是每个类，每个成员都有对应的元素（或属性）存在，

//        但有时我们并不希望某些类的成员在对应的XML文档中出现，例如我们不希望City类的description成员出现在XML文档中，可以使用下面方法：

        xstream.omitField(City.class, "description");

        String s = xstream.toXML(list);

        System.out.println(s);

    }
