for 循环中的 Selenium 过时元素引用

我使用Windows10，Chrome版本89.0.4389.9，vscode，python

该代码仅循环一次，然后出现以下错误。

table = driver.find_element_by_xpath('//*[@id="frm"]/table')
tbody = table.find_element_by_tag_name("tbody")
rows = tbody.find_elements_by_tag_name("tr")
# btns = driver.find_element_by_xpath('//*[@id="frm"]/table/tbody/tr[*]/td[2]/a')

for index, value in enumerate(rows):
    body=value.find_elements_by_tag_name("td")[1]

    body.click()
    sleep(2)
    
    driver.back()
    sleep(2)

Traceback (most recent call last):
  File "d:/Study/Companylist/program/pandastest.py", line 80, in <module>
    body=value.find_elements_by_tag_name("td")[1]
  File "D:\Anaconda\lib\site-packages\selenium\webdriver\remote\webelement.py", line 320, in find_elements_by_tag_name
    return self.find_elements(by=By.TAG_NAME, value=name)
  File "D:\Anaconda\lib\site-packages\selenium\webdriver\remote\webelement.py", line 684, in find_elements
    return self._execute(Command.FIND_CHILD_ELEMENTS,
  File "D:\Anaconda\lib\site-packages\selenium\webdriver\remote\webelement.py", line 633, in _execute
    return self._parent.execute(command, params)
  File "D:\Anaconda\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "D:\Anaconda\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

似乎我找到了解决方案，但可以保护它是最好的，将进一步深入研究：

elements = driver.find_elements(By.CSS_SELECTOR, 'div.g')
for n, el in enumerate(elements):
    elements = driver.find_elements(By.CSS_SELECTOR, 'div.g')
    elements[n].click()
    time.sleep(1)
    driver.back()
    time.sleep(1)
driver.quit()

尝试查找元素，然后开始循环并找到相同的结果，并通过枚举函数中的项目编号从该循环中获取项目。
