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",
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。
