Question

我已經寫以下Python代碼來提取項目的價格從flipkart.com

import urllib2 
import bs4 
import re 

item="Wilco Classic Library: Autobiography Of a Yogi (Hardcover)" 
item.replace(" ", "+") 
link = 'http://www.flipkart.com/search/a/all?query={0}&vertical=all&dd=0&autosuggest[as]=off&autosuggest[as-submittype]=entered&autosuggest[as-grouprank]=0&autosuggest[as-overallrank]=0&autosuggest[orig-query]=&autosuggest[as-shown]=off&Search=%C2%A0&otracker=start&_r=YSWdYULYzr4VBYklfpZRbw--&_l=pMHn9vNCOBi05LKC_PwHFQ--&ref=a2c6fadc-2e24-4412-be6a-ce02c9707310&selmitem=All+Categories'.format(item) 
r = urllib2.Request(link, headers={"User-Agent": "Python-urlli~"}) 
try: 
    response = urllib2.urlopen(r) 
except: 
    print "Internet connection error" 
thePage = response.read() 
soup = bs4.BeautifulSoup(thePage) 
firstBlockSoup = soup.find('div', attrs={'class': 'fk-srch-item'}) 
priceSoup=firstBlockSoup.find('b',attrs={'class':'fksd-bodytext price final-price'}) 
price=priceSoup.contents[0] 
print price 

titleSoup=firstBlockSoup.find('a',attrs={'class':'fk-srch-title-text fksd-bodytext'}) 
title=titleSoup.findAll('b') 
print title 

上述代碼時指定「標題」提取執行打印價格沒有問題。

Rs. 138 

但是如下獲得標題：

[<b>Wilco</b>, <b>Classic</b>, <b>Library</b>, <b>Autobiography</b>, <b>Of</b>, <b>a</b>, <b>Yogi</b>, <b>Hardcover</b>] 

其理由將是顯而易見，如果你有看看product page（使用「檢查元素」）

的源代碼現在，我如何提取適當格式的TITLE以便打印：

Wilco Classic Library: Autobiography Of a Yogi (Hardcover) 

Answer 1

只需使用text方法上titleSoup

>>> titleSoup=firstBlockSoup.find('a',attrs={'class':'fk-srch-title-text fksd-bodytext'}) 
>>> titleSoup.text 
u'Wilco Classic Library: Autobiography Of a Yogi (Hardcover)' 

這也將工作：

invalid_tags = ['b'] 
titleSoup=firstBlockSoup.find('a',attrs={'class':'fk-srch-title-text fksd-bodytext'}) 

for tag in invalid_tags: 
    for match in titleSoup.findAll(tag): 
     match.replaceWithChildren() 
print "".join(titleSoup.contents) 

Answer 2

它會更容易從firstBlockSoup標籤拿到冠軍：

>>> firstBlockSoup.attrs['data-item-name'] 
'Wilco Classic Library: Autobiography Of a Yogi (Hardcover)'
