Question

我正在尝试从每次刷新后具有不同ID的元素获取ID，然后打印出来

网站上的元素代码为：<div id="time_2019-03-28 07:36:50.604535">This element has a ID that changes every time the page is loaded</div>

我的代码：

WebElement randomID = driver.findElement(By.xpath("//*[contains(@id, 'time')]"));
        System.out.println("Random ID is " + randomID.getAttribute("id"));

错误：线程“ main”中的异常org.openqa.selenium.NoSuchElementException：否这样的元素：无法找到元素：{“方法”：“ xpath”，“选择器”：“ // * [包含（@id ，'time'）]“}

@Test
    public void p0l0() throws InterruptedException {

        driver.get("file:\\C:\\Users\\pburgr\\Desktop\\p0l0.html");
        Thread.sleep(5000);

        List<WebElement> divsContainingId = driver.findElements(By.xpath("//div[contains(@id,'time')]"));

        String divsContainingIdSize = Integer.toString(divsContainingId.size());
        System.out.println(divsContainingIdSize);

        String id = divsContainingId.get(0).getAttribute("id");
        System.out.println(id);

    }
