I'm sure my regex could be tuned a bit...
require 'open-uri'
jpg = /img src="(.[^"]*\.jpg)"/
open('http://www.apple.com') do |response|
html = response.read
p jpg.match(html)[1]
end

Somehow I've wrecked my Ruby install today, but I think the following should work
require 'open-uri'
jpg = /img src="(.[^"]*\.jpg)"/
open('http://www.apple.com') do |response|
match = jpg.match(response.read)
match.captures.each { |x| print x }
end

Hum.. I still got one result but thank you so much : i've done some search and here's the result :
require 'open-uri'
open('http://www.apple.com') do |response|
response.read.scan(/img src="(.[^"]*\.jpg)"/).each { |x| p x.to_s }
end

require 'open-uri'
open('http://www.apple.com') { |r| r.read.scan(/img src="(.[^"]*\.jpg)"/).each { |x| p x.to_s } }
This code display jpg image url from a web site.
How can we make the code smarter and better ?
Thanks !
