<hr><a name="_details"></a><h2>Detailed Description</h2>
Objects of this class represent a RSS/ATOM feed, which is basically just a source for new articles. When creating a RSSFeed object, you'll just have to provide it with the URL, where the feed can be downloaded from.<p>
This is the generic way to read feeds:<p>
<ul>
<li>
Create a URL object with the location of the feed.<br>
<code> NSURL* url = [NSURL URLWithString:@"http://www.example.com/feed.xml"]; </code> </li>
<li>
Create a RSSFeed object with the URL:<br>
<code> RSSFeed* feed = [RSSFeed initWithURL: url]; </code> </li>
<li>
Fetch the contents of the feed:<br>
<code> enum RSSFeedError err = [feed fetch]; </code> </li>
<li>
Optionally tell the RSSFeed to keep old articles.<br>
<code> [feed setAutoClear: NO]; </code> </li>
<li>
Iterate over the articles contained in the feed. This is analogous to the iteration over a NSArray. <pre>
int i;
for (i=0; i<[feed count]; i++)
{
RSSArticle* myArticle = [feed articleAtIndex: i];
// [...] more code here
}
</pre> </li>
</ul>
