Selenium 2.0 WebDriver IE8 findelement by xpath cannot be evaluated

Question

When I run the following code in Firefox it runs correctly, but in IE8 it says xpath cannot be evaluated or does not result in a WebElement.

webDriver.findEl         


        

Answer 1

IE 8 need this top 3 line compulsory in selenium web driver

   DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer(); 
   ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);

   WebDriver webDriver= new InternetExplorerDriver(ieCapabilities);

Please change Xpath by Id:

 webDriver.findElement(By.id("submitForm")).click();

Answer 2

Could you try as below?

webDriver.findElement(By.xpath("//input[string(@id)='submitForm']")).click()

For IE doesn't have native XPath support, WebDriver use a third-party library called javascript-xpath for this, this may be a bug of it.
