Scrapping using Nokogiri

Scrapping using Nokogiri

I am not able to scrap the price of the product and the output which I get
is as follow for each price
<div class="pu-final">
<span class="fk-font-17 fk-bold">Rs. 1999</span>
</div>
My code is given below
require 'rubygems'
require 'nokogiri'
require 'open-uri'
url =
"http://www.flipkart.com/mens-footwear/shoes/casual-shoes/pr?sid=osp,cil,nit,e1f"
doc = Nokogiri::HTML(open(url))
puts doc.at_css("title").text
doc.css(".gu4,.browse-product").each do |item|
title = item.at_css(".fk-display-block,.title").text
puts title
puts "================="
price = item.at_css(".pu-final")
puts price
end
