How do I get the exact feed.xml/rss.xml/atom.xml path of a website?
For example, I supplied "http://www.example.com/news/today/this_is_a_news", but the rss is pointing to "http://www.example.com/rss/feed.xml", most modern browsers have this features already and I'm curious how did they get them.
Can you cite an example code in ruby, python or bash?
