Here's a short example of how to parse an RSS feed using Ruby.

require 'rss'
require 'open-uri'

open('https://www.chrisjmendez.com/rss/') do |http|
  response = http.read
  result = RSS::Parser.parse(response, false)
  items = result.items

  items.each do |item|
    puts "Title:" + item.title + "\n" + item.link + " \n" + item.description + "\n"
  end
end
Open a URL, parse an RSS feed.
