I'm trying to click on every possible course links on this page, but it gave me this error:

Message: stale element reference: element is not attached to the page document

This is my code:

driver = webdriver.Chrome()
driver.get('https://catalog.maryville.edu/preview_program.php?catoid=18&poid=3085&_ga=2.22513656.232086776.1594848572-196623372.1594848572')
driver.implicitly_wait(10)
links = driver.find_elements_by_xpath('//*[@id="table_block_n2_and_content_wrapper"]/table/tbody/tr[2]/td[1]/table/tbody/tr/td/table/tbody/tr[2]/td/div/div/ul/li/span/a')

for link in links:
    driver.execute_script("arguments[0].click();", link)
    time.sleep(3)
driver.quit()

Any idea how to fix this?

To click on all the course links on the page https://catalog.maryville.edu/preview_program.php?catoid=18&poid=3085&_ga=2.22513656.232086776.1594848572-196623372.1594848572 you can use either of the following Locator Strategies:

  • Using CSS_SELECTOR:

    driver.get("https://catalog.maryville.edu/preview_program.php?catoid=18&poid=3085&_ga=2.22513656.232086776.1594848572-196623372.1594848572")
links = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "li.acalog-course>span>a")))
for link in links:
    link.click()
    time.sleep(3)
driver.quit()

  • Using XPATH:

    driver.get("https://catalog.maryville.edu/preview_program.php?catoid=18&poid=3085&_ga=2.22513656.232086776.1594848572-196623372.1594848572")
links = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//li[@class='acalog-course']/span/a")))
for link in links:
    link.click()
    time.sleep(3)
driver.quit()

  • Note : You have to add the following imports:

    from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

  • Hello, thanks for your solution. I tried your code, but it skipped some links and there was an error: Message: element click intercepted: Element is not clickable at point (181, 528). Other element would receive the click:
