如何提取p标记和li标记？谢谢！在

Answer 1

注意以下几点：

>>> from BeautifulSoup import BeautifulSoup
>>> html = """ <what you have above> """
>>> Soup = BeautifulSoup(html)
>>> bullets = Soup.findAll('div', {'class': 'productDescriptionWrapper'})
>>> ptags = bullets[0].findAll('p')
>>> print ptags
[<p>A worm worth getting your hands dirty over. With over six feet of crawl space,      Playhut&rsquo;s Wiggly Worm is a brightly colored and friendly play structure.
</p>, <p><strong>Intended for Indoor Use</strong></p>]
>>> print ptags[0].text
A worm worth getting your hands dirty over. With over six feet of crawl space, Playhut&rsquo;s Wiggly Worm is a brightly colored and friendly play structure.
