好的，这只是我试图用Nokogiri解析的html部分。 html中的语义不是很到位，而且我很难获得Nokogiri所需的内容。作为参考，这是我要废弃的网站（http://flix.co.ke/Frontpage/Listings）
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，但凭借我的方法，我无法真正获得所需的所有内容
这是我正在使用的当前脚本
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，我只能获得title电影，one cinema和two contact numbers所以我的示例输出看起来像。

在break标签之后的标题之后有一个描述，我无法得到它，我如何遍历
标签内的所有电影院？以及逗号分隔的电话号码和个人节目时间。
我只是不知道从哪里开始。我希望在这种情况下实现这样的结果
12年奴隶
在战前的美国，来自纽约州北部的一名自由黑人所罗门·诺苏普被绑架并被卖为奴隶。
等
任何帮助都将受到高度赞赏。提前致谢

这是可怕的HTML：/它无效，有451个错误和9个警告。没有任何语义，所以你必须依赖结构，这可能会改变，打破你的刮擦。
尽管如此，您可以通过使用兄弟方法获得每个方法：
doc.css('.min-width div form').each do |node|
description = node.at_css('br').next_sibling.text
puts description.strip
puts '-'*10

html确实没有那么糟糕，而且您使用br + strong走在了正确的轨道上，这就是您要迭代的内容：
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
