什麼是適當的標籤刮那些特定的信息？

我需要通過產品獲得產品列表看起來像：

[名稱，包裝，價格/公斤]

所以，對於第一個我的輸出是三個列表看起來像。

[法國皇家獸醫飲食 - 防過敏DR 21，7千克，4,84]
[法國皇家獸醫飲食 - 防過敏DR 21，14千克，3,71]
[法國皇家獸醫飲食 - 防過敏DR 21,14kg，3,71]

我已經設法在名稱列表中獲取名稱。

from bs4 import BeautifulSoup 
import csv 
import urllib.request 
from collections import * 
import time 
start_time = time.clock() 

page_0=urllib.request.urlopen("http://www.zooplus.co.uk/shop/dogs/dry_dog_food/royal_canin_vet_diet") 
soup_0 = BeautifulSoup(page_0.read(),"html.parser") 
restricted_webpage=soup_0.find_all("tbody", {"class":"product-variants-list"}) 
readable_restricted_webpage=str(restricted_webpage) 
soup_1 = BeautifulSoup(readable_restricted_webpage,"html.parser") 

title=soup_1.find_all("tr", {"style":["background-color:#ffffff;", "background-color:#ededed;"]}) 

soup_title = BeautifulSoup(str(title),"html.parser") 
name=[] 



for b in soup_title.find_all("b"): 
    name.append(str(b).replace("<b>","").replace("</b>",""))

這兩個其他的信息很難得到我。我看不到標籤，我可以用它來獲得（包裝，價格/公斤）夫婦的標籤。

我試了多個標籤，最近我得到了：("td", {"style":"background-color:#ededed;"},{"valign":"top"})但我想我應該使用<span>這種或那種方式？

你將如何繼續傢伙？
