使用selenium webdriver从网页中检索元描述的内容

Question

想要使用webdriver获取页面元描述的内容。

让说，从下面DOM要检索的文本 Test.com provides a complete software solution for creating online tests and managing enterprise and specialist certification programs, in up to 22 languages

<script src="content/js/jquery.min.js"> 
<meta content="Test.com provides a complete software solution for creating online tests and managing enterprise and specialist certification programs, in up to 22 languages." name="description"> 
<meta content="Test.com" name="keywords"> 

我试着用

System.out.println(driver.findElement(By.xpath("//meta[@name='description']")).getText()); 

但上面的代码不会为我工作。

Answer 1

你试图得到一个属性值，所以不是getText()使用getAttribute()：

driver.findElement(By.xpath("//meta[@name='description']")) 
     .getAttribute("content")
