今天看到csdn系统发来的短消息，采用RSS订阅每个类别最新文档我查了下资料，发现有个rsslibj的开源工具可以帮助我们写自己的rss文档当然，我这里讲的是java的实现。首先去下载个rsslibj的包：http://sourceforge.net/project/showfiles.php?group_id=71153参考官方网站的例子程序import com.rsslibj.elements.Channel;public class Writer { public static void main(String[] args) throws InstantiationException, ClassNotFoundException, IllegalAccessException { Channel channel=new Channel(); channel.setDescription("This is my sample channel."); channel.setLink("http://localhost/"); channel.setTitle("My Channel"); channel.setImage("http://localhost/", "The Channel Image", "http://localhost/foo.jpg"); channel.setTextInput("http://localhost/search", "Search The Channel Image", "The Channel Image", "s"); channel.addItem("http://localhost/item1", "The First Item covers details on the first item>", "The First Item") .setDcContributor("Joseph B. Ottinger"); channel.addItem("http://localhost/item2", "The Second Item covers details on the second item", "The Second Item") .setDcCreator("Jason Bell"); System.out.println("The feed in RDF: "+channel.getFeed("rdf")); }}开始怀疑中文会有问题(老外的软件)，测试了一下居然很好，什么问题也没有。你要是熟悉rss文档格式，很容易编写一个标准的rss的writer出来
