Originally reported on Google Code with ID 5459

Here is the html source code of the page:

<!DOCTYPE html>
<html>
<body>

<form action="">
<input type="radio" name="sex" value="female">Male<br>
<input type="radio" name="sex" value="male">Female
</form>

<p>Note: When a user clicks on a radio-button, it becomes checked, and all other radio-buttons
with equal name become unchecked.</p>

</body>
</html>


http://www.w3schools.com/html/tryit.asp?filename=tryhtml_radio

What steps will reproduce the problem?
1. Open the application using selenium webDriver

FirefoxDriver Browser = new FirefoxDriver();
Browser.get("http://www.w3schools.com/html/tryit.asp?filename=tryhtml_radio");



2. Read the text/label of the radio button whose html attribute value="female"
String XPATH = "//input[@value='female']/following-sibling::text()"
String LABEL = Browser.findElement(By.xpath(XPATH)).getText();

3. An InvalidSelectorError exception is raised by WebDriver:
Exception in thread "main" org.openqa.selenium.InvalidSelectorException: The given
selector //input[@value='Red']/following-sibling::text() is either invalid or does
not result in a WebElement. The following error occurred:
InvalidSelectorError: The result of the xpath expression "//input[@value='Red']/following-sibling::text()"
is: [object Text]. It should be an element.

This works fine with Selenium IDE and RC but not with WebDriver.

What is the expected output? What do you see instead?
Ideally it should return the label of the radio button

Selenium version: 2.31.0
OS: Windows XP Professional SP2
Browser: FireFox
Browser version: 19.0.2

Your xpath doesn't return an element; it returns a text node. While this might have
been perfectly acceptable in Selenium RC (and by extension, Selenium IDE), the methods
on the WebDriver WebElement interface require an element object, not just any DOM node
object. WebDriver is working as intended. To fix the issue, you'd need to change the
HTML markup to wrap the text node inside an element, like a <span>.

You can use this code : 

FoundObjectCount = FindWebElementCount(ieDriver,"xpath", "//input[@type='radio' and
(contains(@name,'XXX'))]");

            for(int objcnt = 1; objcnt <= FoundObjectCount; objcnt++) {

                FoundObject = ieDriver.findElement(By.xpath(".//table[@class='XXX']/tbody/tr["+objcnt+"]/td/label"));

                if (FoundObject.getText().equalsIgnoreCase(strSalecycle)) {
                    FoundObject = ieDriver.findElement(By.xpath(".//table[@class='XXX']/tbody/tr["+objcnt+"]/td/input"));
                    ObjectClick(FoundObject);
                    LogInfo("WebElement is Selected of Object id is: "+FoundObject.getAttribute("id"));
                    break;
                } else{
                    LogInfo("WebElement is Not Present in UI");
                    break;
                }

When the HTML looks like this:

<Table>
<TR>
<TD><INPUT id=XXX  value="JUNK" type=radio name=ABCXXX><LABEL for=idXXX>TEXTNEEDTOREAD1
</LABEL>
</TD>
</TR>
<TR>
<TD><INPUT id=XXX  value="JUNK" type=radio name=ABCXXX><LABEL for=idXXX>TEXTNEEDTOREAD2
</LABEL>
</TD>
</TR>
</Table>

This is a "working as intended" issue, so if you've got any sample pages or code that
could help prove otherwise then you'll need to post them - otherwise there is literally
nothing anybody can do because the only piece of code and reproducible material someone
has given has proven WebDriver *is* working as it's intended to do.
