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

问题


I have been trying to run the following code in three different weblinks. Code works fine on one weblink. However, it throws an error message about "Message: stale element reference: element is not attached to the page document". I looked into forum's two previous threads (Python Selenium stale element fix and How to Navigate to a New Webpage In Selenium?) about the same error message but didn't get sort it out the issue. Here is my code:

driver.get('https://github.com/avassalotti')
contributions = driver.find_elements_by_xpath(".//ul[@class='filter-list small']//li") 
print(contributions)
for item in contributions:
    print (item)
    print(item.text)
    item.click()
    time.sleep(3)
    contribution = driver.find_element_by_xpath(".//*[@class='f4 text-normal mb-2']").text
    print(contribution)

Program works for this link (https://github.com/alex) and does not work for (https://github.com/agronholm, https://github.com/avassalotti).

Any advice to fix the issue.

To retrieve the details of contributions avoiding stale element reference you can use the following solution:

  • Code Block:

    from selenium import webdriver
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    
    years = []
    options = webdriver.ChromeOptions() 
    options.add_argument("start-maximized")
    options.add_argument('disable-infobars')
    driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
    driver.get("https://github.com/agronholm")
    contributions = WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='profile-timeline-year-list js-profile-timeline-year-list bg-white js-sticky float-right col-2 pl-5']/ul[@class='filter-list small']//li/a")))
    for item in contributions:
        print(item.get_attribute("innerHTML"))
        years.append(item.get_attribute("href"))
    for year in years:
        driver.get(year)
        print(WebDriverWait(driver, 5).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='js-yearly-contributions']//h2[@class='f4 text-normal mb-2']"))).get_attribute("innerHTML"))
