我想使用 selenium python webdriver 在我的路由器網頁中單擊“無線”鏈接。 下面是html：

我的腳本中有以下行：
driver.find_element_by_xpath('//a[@href="wlswitchinterface0.wl"]').click()
但它不起作用並拋出 NoSuchElementException
NoSuchElementException：消息：無法定位元素：{"method":"xpath","selector":"//a[@href=\\"wlswitchinterface0.wl\\"]"}

問題不在於引號，而是因為您在框架內。
首先，你需要在他的里面切換：
frame = driver.find_element_by_xpath("//frame[@name='menufrm']")
driver.switch_to_frame(frame)
現在，您可以訪問您的鏈接：
driver.find_element_by_xpath("//a[@href='wlswitchinterface0.wl']").click()
在您訪問此框架內所需的所有內容后，您需要切換到默認內容：
driver.switch_to_default_content()

問題似乎與引號有關。 使用以下語法：
driver.find_element_by_xpath("//a[@href='wlswitchinterface0.wl']").click()
