如何使用beauthoulsoup解析date start和date end值？在

<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。在

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]

（注意：您还可以使用beauthoulsoup的text=True方法和findAll一起使用来获得文本，而不是使用如下的regex。）

^{pr2}$

更新：：

要将开始日期和结束日期作为单独的变量，您可以简单地将它们拆分，只需将日期变量拆分如下：

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(' - ')

现在，date_start变量包含开始日期，date_end变量包含结束日期。在
