Beautifulsoup multiple class selector

Question

I want to select all the divs which have BOTH A and B as class attributes.

The following selection

soup.findAll(\'div\', class_=[\'A\', \'B\'])
         


        

Answer 1

for latest BeautifulSoup, you can use regex to search class

code:

import re
from bs4 import BeautifulSoup

multipleClassHtml = """
only A and B
class contain space
except A and B contain other class
only A
only B
no A B
"""

soup = BeautifulSoup(multipleClassHtml, 'html.parser')

bothABClassP = re.compile("A\s+B", re.I)
foundAllAB = soup.find_all("div", attrs={"class": bothABClassP})
print("foundAllAB=%s" % foundAllAB)

output:

foundAllAB=[
only A and B
, 
class contain space
, 
except A and B contain other class
]
