WebScrapping with Selenium and BeaufitulSoup can't find anything-CodePudding

I am trying to extract all the description in the links in the of this website: https://www.sciencedirect.com/browse/journals-and-books?accessType=openAccess&accessType=containsOpenAccess

I tried both with BeautifulSoup and Selenium but I can't extract anything. You can see in the image below the result I got result

Here is the code I am using

options = Options()
options.add_argument("headless")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
ul = driver.find_element(By.ID, "publication-list")
print("Links")
allLi = ul.find_elements(By.TAG_NAME, "li")
for li in allLi:
    print("Links "   str(count)   " "   li.text)

CodePudding user response：

You are missing waits.
You have to wait for elements to become visible before accessing them.
The best approach to do that is with use of WebDriverWait expected_conditions explicit waits.
The following code works

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

options = Options()
options.add_argument("start-maximized")

webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(options=options, service=webdriver_service)
wait = WebDriverWait(driver, 20)

url = "https://www.sciencedirect.com/browse/journals-and-books?accessType=openAccess&accessType=containsOpenAccess"
driver.get(url)
ul = wait.until(EC.visibility_of_element_located((By.ID, "publication-list")))
allLi = wait.until(EC.presence_of_all_elements_located((By.TAG_NAME, "li")))
print(len(allLi))

the output is:
