BeautifulSoup，但是CSS？ [英] BeautifulSoup, but for CSS?

问题描述

BeautifulSoup解析HTML并提供各种在HTML中操作和搜索的方法。 CSS是否有类似的东西？

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

具体来说，我想知道给定的HTML文本是否以粗体呈现。它有一个祖先是< strong> 或< bold> 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这是可能的。

Is this possible without resulting to writing my own library?
