我一直在使用python制作一个简单的selenium脚本。

相信我，我尝试了所有类型的选择器，但不知何故，网络驱动程序总是错过了这一点，我遇到了一个错误。我出错的按钮包含文本"；这就是我&"；。
您在页面上查找的按钮位于iframe内部。这意味着你不能使用硒来访问它里面的信息。据我所知，他们以前没有iframe(这就是为什么你的代码过去可以工作的原因(，但后来改为有了它(可能是为了防止刮取？(。所以要解决这个问题，你只需要查找iframe的url，打开页面，然后在那里查找按钮url。以下是代码的样子：
此行之后：
WebDriverWait(second_tab, 90).until(EC.element_to_be_clickable((By.XPATH, "//tbody[@id='schranka']/tr/td"))).click()
time.sleep(2)
你需要编辑你的代码，使按钮的链接变成这样。
#get iframe url
src = second_tab.find_element_by_xpath('/html/body/div/div[3]/div/div[2]/div/div/iframe').get_attribute('src')
#open iframe url
second_tab.get(src)
#get button
linky = second_tab.find_element_by_xpath("//a[contains(text(),'This is me!')]").get_attribute('href')
#open button link
second_tab.get(linky)
