java - 如何查找div类下的文字

Question

我使用 Internet Explorer 作为浏览器来自动测试，使用 webdriver。我的问题是，如何找到 div 类下的文本？

我的 HTML 看起来像这样:

<div class="welcome_text">
Text-Welcome Vijayanand

我试过像这样使用 XPath

WebElement webelement=driver.findElement(By.xpath("//div[@Class='welcome_text']/div"));
webelement.getText();

但我收到如下所示的错误:

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to find element with xpath == //DIV[@Class='welcome_text']/DIV (WARNING: The server did not provide any stacktrace information)

Command duration or timeout: 656 milliseconds

Answer 1

尝试如下所示的 By.className() 方法。

WebElement webelement=driver.findElement(By.className("welcome_text"));

webelement.getText();
