機械化和Nokogiri：試圖搜索div中的項目

我正在設置抓取工具以獲取產品信息，爲此，我使用機械化，結果是nokogiri，我有一個URL（http://www.megamamute.com.br/brother%205652），它只返回一個產品，但我不能得到正確的正則表達式來獲得這個項目的價格，我要的是裏面的DIV稱爲X-產品：機械化和Nokogiri：試圖搜索div中的項目

，我會喜歡繼續，並檢查如何獲得幾種產品，哈弗Ë幾個div的「X產品」，我無法理解的方式來組裝與所有的數組，並獲得每一個內部的信息，

下面是我的代碼片段，很簡單，

紅寶石片斷

require 'mechanize' 
mechanize = Mechanize.new 
agent= mechanize.get('http://www.megamamute.com.br/brother%205652 
match = agent.search("/xproduct/") 
puts match.html

非常感謝你，

你接近。您可以使用CSS選擇器並添加價格的容器元素的類：

require 'mechanize' 
mechanize = Mechanize.new 
agent= mechanize.get('http://www.megamamute.com.br/brother%205652') 
match = agent.search(".x-product .x-bestPrice") 
puts match.text.strip 

#=> "R$ 2.249,00"
