Python: difference between "lxml" and "html.parser" and "html5lib" with a nice soup?

Question

When using beautiful soup, what is the difference between "lxml" and "html.parser" and "html5lib"? When will you use one over the other and the advantages of each? since I used each of them, they seem to be interchangeable, but I correct that I should use the other from the people here. I would like to strengthen my understanding of these. I read a couple of posts about this here, but they don’t use many of them at all.

Example -

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

Answer 1

From the docs a generalized table of advantages and disadvantages:

• html.parser - BeautifulSoup(markup, "html.parser")

  • : , , Lenient ( Python 2.7.3 3.2.)

  • : ( Python 2.7.3 3.2.2)

• lxml - BeautifulSoup(markup, "lxml")

  • : , Lenient

  • : C

• html5lib - BeautifulSoup(markup, "html5lib")

  • : , , -, HTML5

  • : , Python
