陈旧;元素不再附加到 DOM，不在当前框架上下文中，或者文档已刷新 [英] is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

问题描述

所以我使用 selenium 抓取链接.我可以用循环打印我的链接，但我无法导航到它们，因为我收到以下错误:

So im scraping links using selenium. I can print my links with my loop but I cant navigate to them because I get the following error:

selenium.common.exceptions.StaleElementReferenceException:消息:元素引用过时；元素不再附加到 DOM，不在当前框架上下文中，或者文档已刷新

from selenium import webdriver

driver = webdriver.Firefox()

driver.get("https://www.famousgraphicdesigners.org/")

links = driver.find_elements_by_xpath('//*[@id="pages-2"]/div/ul/li/a')
links_total = len(links)
print("Found", links_total, "total links.\n")

for i in links:
    # print(i.get_attribute('href')) # This works
    driver.get(i.get_attribute('href')) # This doesnt work

driver.quit()

推荐答案

当您导航到新页面时，先前定位的元素将变得陈旧，在这种情况下，links 中的元素，因此您可以't 访问 href 属性.将所有 href 保留在字符串列表中并对其进行迭代

When you navigate to a new page the previously located elements become stale, in that case the elements in links, so you can't access the href attribute. Kee p all the hrefs in a list of strings and iterate over it

links = driver.find_elements_by_xpath('//*[@id="pages-2"]/div/ul/li/a')
links_hrefs = [link.get_attribute('href') for link in links]

for i in links_hrefs:
    driver.get(i)
