我在使用 Python 与 Selenium WebDriver 自动化我们的 Web 应用程序时遇到了一些问题。我登录到应用程序并希望点击“Administration”按钮。但是当我运行我的代码时，它无法通过我的 XPath 找到“Administration”按钮。我尝试了几种不同的方法，但都不奏效。如果我在 Selenium IDE 中输入 //div[7]/div/div 并点击“Find”，它会高亮显示“Administration”按钮。我不知道为什么在运行代码时找不到它。我希望使用 CSS，因为它的速度比 XPath 更快。我需要一些帮助。我收到的错误信息是：
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: {"method":"xpath","selector":"html/body/div[2]/div[2]/div/div[2]/div/div[2]/div/div[7]/div/div"}
我检查了 HTML 元素，完整的 HTML 如下：
