This recipe is very simple. It begins by creating a new RSS object. The RSS class was
constructed earlier in this chapter.
RSS rss = new RSS();
Next, the load method is called to load a RSS feed.
rss.load(url);
Finally, the RSS feed is displayed by calling the RSS object's toString function.
System.out.println(rss.toString());
If you need to access the RSS items directly, you can easily use the getItems function
to obtain a list of RSSItem objects.
Recipe #12.2: Find an RSS Feed
Many web sites contain a special <link> tag that shows you where the RSS feed for
that site resides. By parsing for this <link> tag, you can easily obtain the RSS feed for a
web site. The HTTP Recipes site contains such a tag. If you examine the source at the follow-
ing URL, you will see this tag.
