Problem extracting text from RSS feeds
- by Gautam
Hi, 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.text
end
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
Gautam
