如何使用Selenium Web驱动程序和Java

Question

我尝试了这个，但是没用

WebElement ele= driver.findElement(By.xpath(".//*[@id='navbarTogglerDemo03']/ul/li[4]/a"));

             Actions act=new Actions(driver);

             act.moveToElement(driver.findElement(By.className("dropdown-toggle"))).click().build().perform();
