WebDriver无法使用Java通过xpath查找元素

selenium

以下是使用Java的WebDriver代码段:

        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.google.pl/");
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); 
        WebElement element = driver.findElement(By.name("q")); 
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
WebElement query = driver.findElement(By.xpath("//html/body/div[2]/span/center/form/table/tbody/tr/td[2]/div/div/input"));

query.sendKeys("asd");

执行代码后,出现以下异常:

线程“主”中的异常org.openqa.selenium.NoSuchElementException:无法找到元素:{“方法”:“
xpath”,“选择器”:” // html / body / div [2] / span / center / form / table /
tbody / tr / td [2] / div / div / input“}系统信息:os.name:’Windows

我的代码有什么问题?

@ user729076:您为Google文本字段编写的xpath“ // html / body / div [2] / span / center /
form / table / tbody / tr / td [2] / div / div / input”不正确。Google文本的HTML字段如下:

<input type="text" value="" autocomplete="off" name="q" class="gbqfif" id="gbqfq" style="border: medium none; padding: 0pt; margin: 0pt; height: auto; width: 100%; background: url(&quot;data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw%3D%3D&quot;) repeat scroll 0% 0% transparent; position: absolute; z-index: 6; left: 0px; outline: medium none;" dir="ltr" spellcheck="false">

基于以上HTML,您可以仅使用id或xpath,如下所示:按id:

driver.findElement(By.id("gbqfq")).sendKeys("some text");

通过xpath:

driver.findElement(By.xpath("//input[@id='gbqfq']")).sendKeys("some text");
