好吧，這只是我試圖解析使用Nokogiri的一部分HTML。 html中的語義並不完整，我正在用Nokogiri獲得想要的內容。作爲參考，這是我想要廢除的網站（http://flix.co.ke/Frontpage/Listings）

到目前爲止，我能夠獲得電影的標題，一個電影院和兩個電話號碼，但與我的方法我不能真正得到所有內容所需

這是我使用

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 

有了這個我目前的劇本我只能夠得到電影的title，one cinema和two contact numbers所以我的樣本輸出的模樣。

(continued...) 

有，只是在休息標記後稱號後的描述，我無法得到這一點，並我怎麼通過
標籤內的所有電影院循環？以及逗號分隔的電話號碼和個人演出時間。

我只是不知道從哪裏開始。我會想取得這樣的成績對於這種情況

• 12年從

• 在戰前美國，所羅門·諾薩普，一個自由的黑人男子從紐約州北部，被綁架並賣入奴隸制。

• 世紀Cinemax的 - 結 12:10，19:10，21:40
• 福克斯影城沙立 11:00，14:00，18:00，20:40

etc

任何幫助將不勝感激。在此先感謝

Answer 1

電影院你循環html真的不是那麼糟糕，並且你在br + strong的正確軌道上，這就是你想要迭代的東西：

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 

Answer 2

這是可怕的HTML：/它是無效的451錯誤和9警告。沒有語義，所以你必須依靠可能會改變的結構，打破你的刮擦。

然而，你可以通過使用同級方法獲得每一種：

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