我使用下面的代码从下面的HTML值：我想使用Selenium在一个HTML表格中点击链接
//findTables(driver);
WebElement content = driver.findElement(By.id("tblTaskForms"));
List<WebElement> elements = content.findElements(By.className("form-name name-column assets-Tag ng-binding"));
WebElement myid = content.findElement(By.xpath("//tbody/tr[2]/td[2])[2]"));
当我运行代码的异常是越来越抛出以上。如果您有任何反馈，请让我知道。谢谢
