Problem extracting text from RSS feeds

I am new to the world of Ruby and Rails.

I have seen rails cast 190 and I just started playing with it. I used selector gadget to find out the CSS and XPath

I have the following code..

require 'rubygems'require 'nokogiri'require 'open-uri'url = "http://www.telegraph.co.uk/sport/football/rss"doc = Nokogiri::HTML(open(url))  doc.xpath('//a').each do |paragraph|puts paragraph.textend

When I extracted text from a normal HTML page with css, I could get the extracted text on the console.

But when I try to do the same either with CSS or XPath for the RSS Feed for the following URL mentioned in the code above, I dont get any output.

How do you extract text from RSS feeds??

I also have another silly question.

Is there a way to extract text from 2 different feeds and display it on the console

something like

url1 = "http://www.telegraph.co.uk/sport/football/rss"url2 = "http://www.telegraph.co.uk/sport/cricket/rss"

Looking forward for your help and suggestions

Thank You
