Question

我使用python和selenium，用firefox驱动程序加载页面。将显示一个链接列表，我可以收集这些链接，但是当我尝试依次单击每个链接时（该链接前进到包含我抓取的数据的页面），然后返回到带有链接列表的上一页并单击下一个，将引发Stale Element Exception。已经看了10多个视频，阅读了20多个有关应该如何解决此问题的帖子，尝试了多种选择都无效。

这是我的代码。

links = driver.find_elements_by_partial_link_text('2019 TRC')
    for link in links:
        link.click()
        get_data()  #this gathers data on the new page appearing after clicking the link
        driver.back()  #this travels back to page with link list, but then fails with stale element exception

我的目的是将链接收集到一个列表中，在列表上单击并单击每个链接（这将打开一个包含数据的新页面），以迭代该列表，收集数据，返回包含链接的页面，单击下一个链接，直到链接列表已用完。

我尝试了所有这些选项，但都失败了。

#1

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         links = driver.find_elements_by_xpath("//*[contains(text(), '2019 TRC')]")
#         case.click()
#     driver.back()


#2

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         driver.find_elements_by_xpath("//*[contains(text(), '2019 TRC')]")
#         case.click()
#     driver.back()


#3 - This just keeps going back after returning to case list page

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         driver.find_elements_by_xpath("//*[contains(text(), '2019 TRC')]")
#     time.sleep(1)
#     driver.back()

#4 Stays at the link list page

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         driver.find_elements_by_xpath("//*[contains(text(), '2019 TRC')]")
#         case.click()
#     time.sleep(1)
#     driver.back()


#5 stays at the link list page

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         links = driver.find_elements_by_xpath("//*[contains(text(), '2019 TRC')]")
#         case.click()
#     time.sleep(1)
#     driver.back()

#6  Changed elements to element (single) and this stays as the link list page again

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         driver.find_element_by_xpath("//*[contains(text(), '2019 TRC')]")
#         case.click()
#     time.sleep(1)
#     driver.back()

#7  Stayed on the first case detail page
#
# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         driver.find_element_by_xpath("//*[contains(text(), '2019 TRC')]")
#     case.click()
#     driver.back()


#8  DId not work using links= instead of just the driver.

# for case in links:
#     try:
#         case.click()
#     except StaleElementReferenceException:
#         links = driver.find_element_by_xpath("//*[contains(text(), '2019 TRC')]")
#     case.click()
#     driver.back()

我什至尝试查找带有“ by_partial_link_text”或“ by_id”的链接，并且仍然存在相同的错误表面。

如果您迅速将此问题标记为已回答，请注意，我刚才已经阅读了Stackoverflow上的其他文章，但没有一个提供有效的解决方案。我尝试了其中大约五个。

StaleElementReferenceException，以前没有帖子建议或YouTube视频解决了问题
