How should I do a loop a nokogiri search in ruby?
- by kim
I have the following that I retreive the title of each url from an array that contains a list of urls.
require 'rubygems'
require 'nokogiri'
require 'open-uri'
@urls = ["http://google.com", "http://yahoo.com", "http://rubyonrails.org"]
@found_titles = Array.new
@found_titles[0] = Nokogiri::HTML(open("#{@urls[0]}")).search("title").inner_html
#this can go on forever...but
#@found_titles[1] = Nokogiri::HTML(open("#{@urls[1]}")).search("title").inner_html
#@found_titles[2] = Nokogiri::HTML(open("#{@urls[2]}")).search("title").inner_html
puts "#{@found_titles[0]}"
How should i form a loop method for this so i can get the title even when the list in @url array gets longer.
