Question

我想从这个页面获得价格

http://www.fastfurnishings.com/Aura-Floor-Lamp-p/lsi_ls-aurafl-gy-gn.htm

价格在

之内

<font class="text colors_text"><b>Retail Price:<s></b> $199.00 </font><br /><b><FONT class="pricecolor colors_productprice"></s>Price: <span itemprop='price'>$139.00</span> </font></b>

我希望这个价格为139.00美元

我有下面的代码，但它没有找到价格

html = urllib2.urlopen(value)
soup = BS(html)
foundPrice = soup.findAll('span', {'itemprop':'price'})
if found is not None:
    print "found a price"
else:
    print" No Lunk"

Answer 1

在以下代码中：

foundPrice = soup.findAll('span', {'itemprop':'price'})
if found is not None:

您已将findAll的结果分配给foundPrice，但if语句比较found。

请尝试以下操作：

import urllib2

from bs4 import BeautifulSoup


url = 'http://www.fastfurnishings.com/Aura-Floor-Lamp-p/lsi_ls-aurafl-gy-gn.htm'
u = urllib2.urlopen(url)
try:
    soup = BeautifulSoup(u)
finally:
    u.close()

span = soup.find('span', {'itemprop':'price'})
if span is not None:
    print span.string
else:
    print 'Not found'

美丽的汤获得<s>标签或获得价格</s>
