好吧，这只是我试图解析使用Nokogiri的一部分HTML。 html中的语义并不完整，我正在用Nokogiri获得想要的内容。作为参考，这是我想要废除的网站（http://flix.co.ke/Frontpage/Listings）解析内容不在html标签Nokogiri

到目前为止，我能够获得电影的标题，一个电影院和两个电话号码，但与我的方法我不能真正得到所有内容所需

这是我使用

require 'rubygems' 
require 'nokogiri' 
require 'open-uri' 

url = "http://flix.co.ke/Frontpage/Listings" 
doc = Nokogiri::HTML(open(url)) 

doc.css(".min-width div form").each do |entry| 
    title = entry.at_css("span").text 
    puts title 

    cinema = entry.at_css("br+ strong").text 
    puts cinema 

    phone = entry.at_css("a").text 
    puts phone 

    puts entry.at_css("a").next_element.text 
end

有了这个我目前的剧本我只能够得到电影的title，one cinema和two contact numbers所以我的样本输出的模样。

(continued...)

有，只是在休息标记后称号后的描述，我无法得到这一点，并我怎么通过
标签内的所有电影院循环？以及逗号分隔的电话号码和个人演出时间。

我只是不知道从哪里开始。我会想取得这样的成绩对于这种情况

任何帮助将不胜感激。在此先感谢

包含有效的HTML片段，而不是提取。为了帮助你，我们必须跳过篮球。 –

答

电影院你循环html真的不是那么糟糕，并且你在br + strong的正确轨道上，这就是你想要迭代的东西：

doc.search('.min-width div form').each do |form| 
    title = form.at('span').text 
    description = form.at('br').next.text 

    form.search('br + strong').each do |el| 
    cinema = el.text 
    phones = [] 
    while next_el = el.at('+ a', '+ br + a') 
     el = next_el 
     phones << el.text 
    end 
    times = el.at('+ br').next.text   
    end 
end

我不能强调这是多么有帮助。谢谢一堆！ ;-) –

这是可怕的HTML：/它是无效的451错误和9警告。没有语义，所以你必须依靠可能会改变的结构，打破你的刮擦。

然而，你可以通过使用同级方法获得每一种：

doc.css('.min-width div form').each do |node| 
    description = node.at_css('br').next_sibling.text 
    puts description.strip 
    puts '-'*10 
end
