新浪RSS解析，比较老的一个话题啦，新浪rss解析,代码结构不复杂Main.

代码结构不复杂Main.java 主类News.java和Outline.java 一条新闻对象和一个新闻频道对象PublicUtils.java工具类很简单，就一个读取配置文件中新浪RSS的地址的方法Dom4jXmlParser.java 这个类是核心，根据工具类读取进来的地址进行解析XML文档，获取到各个频道的集合，然后再迭代解析各个频道内的XML获取新闻的集合，用News（新闻）和Outline（频道）封装

文件：resource_sina.properties内容：url=http://rss.sina.com.cn/sina_all_opml.xml作用：存放新浪RSS接口地址的配置文件
