找到BeautifulSoup特定标签 [英] Find a specific tag with BeautifulSoup

问题描述

我可以很容易BS穿越通用的标签，但我不知道如何找到特定的标签。例如，我怎么能找到＆LT的所有出现; DIV的风格=WIDTH = 300像素;＆GT; ？这可能与BS？

I can traverse generic tags easily with BS, but I don't know how to find specific tags. For example, how can I find all occurances of <div style="width=300px;">? Is this possible with BS?

推荐答案

下面应该工作

soup = BeautifulSoup(htmlstring)
soup.findAll('div', style="width=300px;")

有两种方法来搜索标记。
