BeautifulSoup - 修改在一块HTML的各个环节？ [英] BeautifulSoup - modifying all links in a piece of HTML?

问题描述

我需要能够修改HTML文档中的每一个环节。我知道我需要使用 SoupStrainer ，但我不是如何实现它正面100％。如果有人可以直接我一个很好的资源或者提供code为例，这将会是非常AP preciated。

I need to be able to modify every single link in an HTML document. I know that I need to use the SoupStrainer but I'm not 100% positive on how to implement it. If someone could direct me to a good resource or provide a code example, it'd be very much appreciated.

感谢。

推荐答案

也许像这样的工作吗？ （我没有在我面前一个Python间preTER，可惜）

Maybe something like this would work? (I don't have a Python interpreter in front of me, unfortunately)

from BeautifulSoup import BeautifulSoup
soup = BeautifulSoup('<p>Blah blah blah <a href="http://google.com">Google</a></p>')
for a in soup.findAll('a'):
  a['href'] = a['href'].replace("google", "mysite")

result = str(soup)
