Question

我一直试图在三个不同的Web链接中运行以下代码。代码可以在一个Web链接上正常工作。但是，它将引发有关“消息：陈旧元素引用：元素未附加到页面文档”的错误消息。我查看了论坛的前两个线程（Python Selenium stale element fix和How to Navigate to a New Webpage In Selenium?），发现了相同的错误消息，但是并没有解决问题。这是我的代码：

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)

程序适用于此链接（https://github.com/alex），不适用于（https://github.com/agronholm，https://github.com/avassalotti）。

任何解决此问题的建议。

要检索有助于避免 陈旧元素引用 的贡献的详细信息，可以使用以下解决方案：

代码块：

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"))
