Selenium 没有通过它的 xPath 找到元素

Question

Trying to upload some image from Facebook by its xPath, without lucky, any other way to do it?

Java:

var xPathContato = "//*[@id=\"mount_0_0_lv\"]/div/div[1]/div/div[3]/div/div/div[1]/div[1]/div/div/div[4]/div/div/div/div/div/div/div/div/div[3]";
WebElement wb = webDriver.findElement(By.xpath(xPathContato));

String image = wb.getAttribute("src");
 
URL imageURL = new URL(image );
BufferedImage saveImage = ImageIO.read(imageURL);
 
ImageIO.write(saveImage, "png", new File("facebook-img"));

Error:

Caused by: org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="mount_0_0_lv"]/div/div[1]/div/div[3]/div/div/div[1]/div[1]/div/div/div[4]/div/div/div/div/div/div/div/div/div[3]"}

I think you are mixing something up. The elemnt doesn't really exit in the page you are uploading into selenium, otherwise it would be shown without any problems, but the element exist basically only in your developer toolbar of your browser.
