如何在Selenium Webdriver（Java）中找到包含特定文本的元素？

Question

我試圖從每個刷新后具有不同ID的元素獲取id然后打印它

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

我的代碼：

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

錯誤：線程“main”中的異常org.openqa.selenium.NoSuchElementException：沒有這樣的元素：無法找到元素：{“method”：“xpath”，“selector”：“// * [contains（@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);

    }
