谁能帮我如何匹配这个元素，我想从国家列表中单击加拿大。Selenium (IDE/WebDriver) 未找到该元素。我在 Webdriver 中尝试过：
driver.FindElement(By.XPath(".//*[@class='slick-viewport']/*[@class='grid-canvas']/*[@class='ui-widget-content slick-row odd']/*[@class='slick-cell l1 r1 active selected']")).click();
Firepath 给出了这个 XPath：
.//*[@id='assetsTable']/div[5]/div/div[5]/div[2]
这些都不起作用。显然，我做得不对。id 是动态生成的，并且是嵌套的，所以我发现很难解决。任何人都可以看看并告诉我定位器的正确方法吗？
非常感谢
