如何使用Selenium和Java从html提取文本2？

Question

Using Java with Selenium and Eclipse and Chrome. 在Selenium，Eclipse和Chrome中使用Java。 I was on the page in Chrome I wanted to find an xpath for, so I did an inspect, and then right-click->copy->xpath and it returned the following: 我当时在Chrome上想要查找xpath的页面上，所以进行了检查，然后右键单击-> copy-> xpath，它返回以下内容：

 //*[@id="queueForm"]/div[1]/span[3]/text()[2]

So I did a 所以我做了一个

 // driver is an instance of ChromeDriver
 String xp = "//*[@id="queueForm"]/div[1]/span[3]/text()[2]";
 WebElement ele = driver.findElement(By.xpath(xp));

and I received an error message that that returned an object and not WebElement. 并且我收到一条错误消息，该错误消息返回了一个对象而不是WebElement。 Anyone run into this situation before? 有人遇到过这种情况吗？ The HTML is like HTML就像

<span class="displayOption" style="float:right;">
        Page <input id="gotoresultpage" type="text" onkeypress="javascript:fncCaptureEnter(this);" size="1" maxlength="4" tabindex="1" value="1" class="navigationMenu" style="width:20px;text-align:right"> of 2
        <input type="button" tabindex="1" value="Go" id="pageGo" name="pageGo" class="navigationButton" onclick="g_objQueueUiController.fncGo();">

        <span class="recordNavigationBack"></span>

        <span class="recordNavigationForwardEnabled" id="pageNext" name="pageNext" onclick="g_objQueueUiController.fncGoToPage('2')"></span>

</span>

You can see text "Page" in there and a bit later "of 2". 您可以在其中看到文本“ Page”，稍后可以看到“ of 2”。 The page number is in the input box. 页码在输入框中。

So I am trying to get the "of 2" text. 因此，我尝试获取“ 2个”文本。 I already got the page number from the value of the input box, but not sure how to get the "of 2". 我已经从输入框的值中获得了页码，但是不确定如何获取“ 2”。

Answer 1

try this 尝试这个

xpath = //span[@class='displayOption']//input[@id='gotoresultpage']

driver.findElement(By.xpath(xpath))).getAttribute("value");

Answer 2

Remove this text() from the end of your XPath expression, the value returned from the WebDriver.find() function must be a Node , not the text. 从XPath表达式的末尾删除此text() ，从WebDriver.find（）函数返回的值必须是Node ，而不是文本。

So you need to amend your code to something like: 因此，您需要将代码修改为：

//input[@id='gotoresultpage']

example code: 示例代码：

WebElement someElement = driver.findElement(By.xpath("//input[@id='gotoresultpage']"))
String text = someElement.getText();

While running Selenium Web-driver, sometimes the page takes a bit more time to load DOM at the back-end and page itself which causes the web-driver to fail a test step. 在运行Selenium Web驱动程序时，有时页面需要花费更多时间在后端和页面本身上加载DOM，这导致Web驱动程序无法通过测试步骤。 Try using 'Waits' in your code so that it provides a bit more time to load your page and DOM. 尝试在代码中使用“等待”，以便它提供更多时间来加载页面和DOM。 Try using this code for wait: 尝试使用以下代码等待：

WebDriverWait wait = new WebDriverWait(driver, 15); WebDriverWait wait =新的WebDriverWait（driver，15）; wait.until(ExpectedConditions.elementToBeClickable(By.xpath(""))); wait.until（ExpectedConditions.elementToBeClickable（By.xpath（“”））））;

Or simply use thread.sleep: Thread.sleep(Long Millis, Int nanos); 或者简单地使用thread.sleep：Thread.sleep（Long Millis，Int nanos）;

(Example: Thread.sleep(5000, 50000);this will implement 5 seconds sleep between your test steps) （示例：Thread.sleep（5000，50000）；这将在您的测试步骤之间实现5秒钟的睡眠）

Also, pls note that auto generated xpaths are dynamic which may update on your next test script execution so be vigilant while selecting a web element to be found through web-driver. 另外，请注意，自动生成的xpath是动态的，可能在您下一次测试脚本执行时更新，因此在选择要通过Web驱动程序找到的Web元素时要保持警惕。

The text of 2 is a text node , so to extract the text you need to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies : 2的文本是一个文本节点 ，因此要提取文本，需要为visible_of_element_located visibility_of_element_located()引入WebDriverWait ，并且可以使用以下任一定位器策略：

Using cssSelector : 使用cssSelector ：

 System.out.println(((JavascriptExecutor)driver).executeScript('return arguments[0].childNodes[3].textContent;', new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("#queueForm>div span.displayOption[style*='right']")))).toString());

Using xpath : 使用xpath ：

 System.out.println(((JavascriptExecutor)driver).executeScript('return arguments[0].childNodes[3].textContent;', new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id="queueForm"]/div//span[@class='displayOption' and contains(@style, 'right')]")))).toString());

I did the test in following link : https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_form 我在以下链接中进行了测试： https : //www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_form

Here is the HTML 这是HTML

 <!DOCTYPE html> <html> <body> <form action="/action_page.php" id="form1"> First name: <input type="text" name="fname"><br> <input type="submit" value="Submit"> </form> <p>The "Last name" field below is outside the form element, but still part of the form.</p> Last name: <input type="text" name="lname" form="form1"> </body> </html>

I got the text "First name" of form 我得到了表格的“名字”文字

Here my code 这是我的代码

driver.switchTo().frame("iframeResult");
driver.findElement(By.id("form1")).getText();

Last line return "First name" 最后一行返回“名字”
