Android--使用XMLPull解析xml

在Android中极力推荐的xmlpull方式解析xml。xmlpull不仅仅可以使用在Android上，同样也适用于javase，但在javase环境下，你需要自己去获取xmlpull所依赖的类库。
        环境：        

    kxml2-2.3.0.jar

    xmlpull_1_1_3_4c.jar

以上两个jar分别从以下网站下载:

http://www.xmlpull.org/    xmlpull

    kxml

xml文件:

注：若工程中缺少kxml2-2.3.0.jar文件则会报以下异常信息:

你应该添加kxml2-2.3.0.jar包到你的classpath下
