         </html>

我有我的腳本以下行：

driver.find_element_by_xpath('//a[@href="wlswitchinterface0.wl"]').click()

但它不工作，並拋出NoSuchElementException異常

NoSuchElementException異常：消息：找不到元素： {「method」：「xpath」，「selector」：「// a [@href = \」wlswitchinterface0.wl \「]」}

問題不在於引號，而是因爲您在幀內。

首先，你需要他的內線切換：

frame = driver.find_element_by_xpath("//frame[@name='menufrm']") 
driver.switch_to_frame(frame)

現在，您可以訪問鏈接：在您訪問所有你需要這個框架內

driver.find_element_by_xpath("//a[@href='wlswitchinterface0.wl']").click()

，你需要切換到默認內容：

driver.switch_to_default_content()

它的工作原理。謝謝@Striter。但是我想知道爲什麼Selenium IDE生成的代碼無法處理這些幀切換？ –

這是因爲Selenium IDE不關心框架，它可以看到整個網頁。 Selenium WebDriver一次只能關注一幀。 – Mobrockers

由於框架（或iframe）意味着與上下文基礎不同的上下文。 –

這個問題似乎與報價。使用以下語法：

driver.find_element_by_xpath("//a[@href='wlswitchinterface0.wl']").click()
