BeautifulSoup，但对于CSS？ [英] BeautifulSoup, but for CSS?

问题描述

BeautifulSoup解析HTML，并提供各种方式来操纵和HTML中进行搜索。是否有一个CSS相似的地方？

BeautifulSoup parses HTML and offers various ways to manipulate and search within HTML. Is there something similar for CSS?

我特别想知道，如果给定的HTML文本呈现为粗体即可。无论是它有一个祖先是＆LT;强＆GT; 或＆LT;大胆＆GT; 标签（这是可以做到与BeautifulSoup），或者它有一个祖先（或自己）有CSS与字体重量属性：粗体

Specifically, I'd like to know if a given HTML text is rendered as bold. Either it has an ancestor that is the <strong> or the <bold> tag (which can be done with BeautifulSoup), or it has an ancestor (or itself) that has CSS attributes with font-weight: bold.

而不会导致以写我自己的图书馆是这可能吗？

Is this possible without resulting to writing my own library?
