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'])
however selects all the divs which have EITHER A or B in their class attributes. Classes may have many other attributes (C, D, etc) in any order, but I want to select only those ones that have both A and B.
Use css selectors
instead:
soup.select('div.A.B')
