Locate and grab RSS Feed link from other site

Locate and grab RSS Feed link from other site

I want to find an rss link on a page (not "local", from another website) and grab that rss feed, display it in my site.

If it needs further explanation just ask and ill try to be clearer..

So far i've found this code:

  1. var link_elements = $('link[type="application/rss+xml"]');
I dont really know what the code above does but ive gotten that suggestion from someone..

P.S. The site im grabbing an RSS feed from only has 1 rss link on the website, not multple..
