BeautifulSoup检测NoFollow

Question

我正在寻找BeautifulSoup来检测链接中的NoFollow/DoFollow。有什么简单的方法可以做到这一点吗？我正在寻找一个选项，将忽略大小写敏感，并与不同的方式放置rel=nofollow的工作。

我有这个，但它不工作：

        if 'nofollow' in link:
            print "Nofollow"
        else:
            print "Dofollow"

编辑:实际上我想通了，下面是代码：

        if link in soup.find_all(rel="nofollow"):
            print "NoFollow"
        else:
            print "Dofollow"

看起来它是工作的，我将测试它更多，并编辑，如果有例外的需要。

Answer 1

links = soup.find_all(rel=True)  # This will find all links which has an attribute named 'rel'
for link in links:
    print link['rel']   # This will print the value of rel attribute while looping through the earlier found links
