Question

Is there a way to read from an RSS feed using Node.js, possibly, in Real-time?

Thanks

Answer 1

尝试node-feedparser

Answer 2

Try this . It's a real-time RSS parser tutorial. Enjoy.

Answer 3

Try node-rss . It is unstable though but you should be able to use it as an example to write your own RSS parser.

/**********************************************************************
Example One:
Getting a remote RSS feed and parsing
rss.parseURL(feed_url, use_excerpt, callback);
**********************************************************************/
// URL of the feed you want to parse
var feed_url = 'http://feeds.feedburner.com/github';

var response = rss.parseURL(feed_url, function(articles) {
    sys.puts(articles.length);
    for(i=0; i<articles.length; i++) {
    sys.puts("Article: "+i+", "+
         articles[i].title+"\n"+
         articles[i].link+"\n"+
         articles[i].description+"\n"+
         articles[i].content
        );
    }
});

Answer 4

Answer 5

Not sure about realtime.. I have seen most people poll the RSS URLs using SetTimeout like the example below..

function updateFeeds() {
    // Do some work.  Possibly async
    // Call done() when finished.
}

function done() {
    setTimeout( updateFeeds, 1000 * 60 );
}

Or you could try using a Task Queue like Node-Resque .

But here are a couple of libraries that you could source from..

A simple node.js rss parser using sax-js or Node FeedParser

I found a pretty good intro to Node JS that includes a RSS parsing example.. Here

As I make my way through my project, I will update this answer with any new findings.. Hope this helped.
