如何使用 beautifulsoup 解析日期开始和日期结束值？

<h2 name="PRM-013113-21017-0FSNS" class="pointer">
    <a name="PRM-013113-21017-0FSNS">Chinese New Year Sale<br>
       <span>February 8, 2013 - February 10, 2013</span>
    </a>
</h2>

Answer 1

像这样的东西。

import re
from BeautifulSoup import BeautifulSoup

html = '<h2 name="PRM-013113-21017-0FSNS" class="pointer"><a name="PRM-013113-21017-0FSNS">Chinese New Year Sale<br><span>February 8, 2013 - February 10, 2013</span></a></h2>'
date_span = BeautifulSoup(html).findAll('h2', {'class' : 'pointer'})[0].findAll('span')[0]
date = re.findall(r'<span>(.+?)</span>', str(date_span))[0]

（PS：您也可以使用 BeautifulSoup 的text=True方法 withfindAll来获取文本，而不是使用正则表达式，如下所示。）

from BeautifulSoup import BeautifulSoup

html = '<h2 name="PRM-013113-21017-0FSNS" class="pointer"><a name="PRM-013113-21017-0FSNS">Chinese New Year Sale<br><span>February 8, 2013 - February 10, 2013</span></a></h2>'
date = BeautifulSoup(test).findAll('h2', {'class' : 'pointer'})[0].findAll('span')[0]
date = date.findAll(text=True)[0]

更新：：

要将开始日期和结束日期作为单独的变量，您可以简单地拆分它们，您可以简单地拆分日期变量，如下所示：

from BeautifulSoup import BeautifulSoup

html = '<h2 name="PRM-013113-21017-0FSNS" class="pointer"><a name="PRM-013113-21017-0FSNS">Chinese New Year Sale<br><span>February 8, 2013 - February 10, 2013</span></a></h2>'
date = BeautifulSoup(test).findAll('h2', {'class' : 'pointer'})[0].findAll('span')[0]
date = date.findAll(text=True)[0]
# Get start and end date separately
date_start, date_end = date.split(' - ')

nowdate_start变量包含开始日期，date_end变量包含结束日期。
