How to get the RSS URL in javascript?

September 26, 2006 12:24 PM

How do I access the RSS URL defined in the tag of a page, using javascript?

I want to use a bookmarklet to capture the RSS URL of the page I'm looking at. I'm sure there must be a document.something property that I could access, but I don't know enough javascript to figure it out.

The bookmarklet was stripped by Mefi's XSS filtering - I figured that would happen. Visit Laughing Meme for the unfiltered bookmarklet.

I wrote one that turns out to be nearly the same as the previous answer, but I don't want it to be for naught:

javascript:var links = document.getElementsByTagName('link'); for (var i = 0; links[i] && links[i].getAttribute('type') != 'application/rss+xml'; ++i); if (links[i] && links[i].hasAttribute('href')) alert(links[i].getAttribute('href'));

Best answer: This one will alert for all if there are multiples instead of just the first

javascript:var links = document.getElementsByTagName('link'); for (var i = 0; links[i]; ++i) { if (links[i].getAttribute('type') == 'application/rss+xml' && links[i].hasAttribute('href')) alert(links[i].getAttribute('href')); }
