假设您在要解析的页面上，Selenium将源HTML存储在驱动程序的page_source属性中。这样，你会加载page_source到BeautifulSoup如下：

In [8]: from bs4 import BeautifulSoup

In [9]: from selenium import webdriver

In [10]: driver = webdriver.Firefox()

In [11]: driver.get('http://news.ycombinator.com')

In [12]: html = driver.page_source

In [13]: soup = BeautifulSoup(html)

In [14]: for tag in soup.find_all('title'):
   ....:     print tag.text
   ....:     
   ....:
