使用ROME去读取解释RSS源

ROME使用JDOM 1.0进行XML的解析，ROME的使用非常简单，下面是一个最简单的例子：
package com.sun.syndication.samples;
import java.net.URL;
import java.io.InputStreamReader;
import com.sun.syndication.feed.synd.SyndFeed;
import com.sun.syndication.io.SyndFeedInput;
import com.sun.syndication.io.XmlReader;
//下面这个类，可以从任意类型的rss、atom中解释数据出来
public class FeedReader {
    public static void main(String[] args) {
        boolean ok = false;
        if (args.length==1) {
            try {
                URL feedUrl = new URL(args[0]);
                SyndFeedInput input = new SyndFeedInput();
                SyndFeed feed = input.build(new XmlReader(feedUrl));
//通过url地址和XmlReader进行解释，自动识别xml的类型
                System.out.println(feed);
                ok = true;
            }
            catch (Exception ex) {
            }
        }

        if (!ok) {
            System.out.println();
            System.out.println(”FeedReader reads and prints any RSS/Atom feed type.”);
            System.out.println(”The first parameter must be the URL of the feed to read.”);
            System.out.println();
            }
        }
}
