python:"lxml"和"html.parser"之间的区别和"html5lib"配上漂亮的汤? [英] python: difference between 'lxml' and "html.parser" and "html5lib" with beautiful soup?

问题描述

使用漂亮的汤时，'lxml'和"html.parser"和"html5lib"有什么区别?您什么时候可以使用另一种方法以及每种方法的优点?从我每次使用的时间来看，它们似乎是可互换的，但我确实得到纠正，我应该使用与此处的人不同的方法.想加深我对这些的理解.我在这里已经阅读了几篇有关此内容的文章，但它们根本没有涉及太多用途.

When using beautiful soup what is the difference between 'lxml' and "html.parser" and "html5lib"? When would you use one over the other and the benefits of each? from the times i used each they seem to be interchangeable but i do get corrected that i should be using a different one from people on here. Would like to strengthen my understanding of these. I have read a couple posts on here about this but they are not going over the uses much in any at all.

示例-

soup = BeautifulSoup(response.text, 'lxml')
