Is there an error with nokogiri and title recent windows build of ruby 1.9.2-p0? I have installed ruby and nokogiri gem. I was following the railscast > **[\#190 Screen Scraping with Nokogiri - RailsCasts](http://railscasts.com/episodes/190-screen-scraping-with-nokogiri)** > > Short Ruby on Rails screencasts containing tips, tricks and tutorials. Great for both novice and experienced web developers. As I am just learning things I thought I would start by running the script from the tutorial. # To change this template, choose Tools | Templates # and open the template in the editor. # To change this template, choose Tools | Templates # and open the template in the editor. # nokogiri\_test.rb require ‘rubygems’ require ‘nokogiri’ require ‘open-uri’ url = “[http://www.walmart.com/search/search-ng.do](http://www.walmart.com/search/search-ng.do)? search\_constraint=0&ic=48\_0&search\_query=batman&Find.x=0&Find.y=0&Find=Find” doc = Nokogiri::HTML(open(url)) puts doc.at\_css(“title”).text doc.css(“.item”).each do |item| title = item.at\_css(“.prodLink”).text price = item.at\_css(“.PriceCompare .BodyS, .PriceXLBold”).text[/ $[0-9.]+/] puts “#{title} - #{price}” puts item.at\_css(“.prodLink”)[:href] end # lib/tasks/product\_prices.rake desc “Fetch product prices” task :fetch\_prices =\> :environment do require ‘nokogiri’ require ‘open-uri’ Product.find\_all\_by\_price(nil).each do |product| url = “[http://www.walmart.com/search/search-ng.do](http://www.walmart.com/search/search-ng.do)? search\_constraint=0&ic=48\_0&search\_query=#{CGI.escape(product.name)} &Find.x=0&Find.y=0&Find=Find” doc = Nokogiri::HTML(open(url)) price = doc.at\_css(“.PriceCompare .BodyS, .PriceXLBold”).text[/ [0-9.]+/] product.update\_attribute(:price, price) end end I keep getting this error.

Any easy way to fix. I have updated gems and made sure all dependencies are covered but no go. Should I go back to 1.9.1 or 1.8.9 ro get compatibility? ---

You’d be much better off bringing this up on the nokogiri mailing list or filing a ticket in their issue tracker. This mailing list is not good for specific third party library technical support. ---
