Как я могу правильно идентифицировать объект с проверкой, а затем очистить его?

Мне нужно почерпнуть с веб-сайта NASDAQ 2 основную информацию: Институциональная собственность и Всего акций в обращении (миллионы)

(здесь пример из XYLEM IN C. Company https://www.nasdaq.com/market-activity/stocks/xyl/institutional-holdings

Проблема в том, что я не могу найти данные! Если я ищу "div", отображается не так много.

Ниже кода 

import pandas as pd
from bs4 import BeautifulSoup
import urllib.request as ur

index = 'XYL'
url = 'https://www.nasdaq.com/market-activity/stocks/' + index + '/institutional-holdings'
print(url)

read = ur.urlopen(url).read() 
soup_is = BeautifulSoup(read,'lxml')
soup_is

ls = []
for l in soup_is.find_all("div"):
    ls.append(l.string)
ls2= list(filter(None,ls))
ls2

Может ли кто-нибудь помочь мне с этим вопросом? Большое спасибо
