How to check if radio button is selected or not using Selenium WebDriver?

In Java, this would do it:

if(driver.findElement(By.id("17390233")).isSelected()){    System.out.println(driver.findElement(By.xpath("//input[@id='17390233']/following-sibling::span[1]")).getText());}

If the radio button is selected, then the text will show. If you want to use the text somewhere, I suggest you put it in a string instead:

String spanText = driver.findElement(By.xpath("//input[@id='17390233']/following-sibling::span[1]")).getText();

Hope this answers your question.

EDIT: Here is an update of other ways to try.

If the className default_shipping_address is unique (e.g. not used anywhere else on the page), you may try locating the element by className:

if(driver.findElement(By.className("default_shipping_address")).isSelected()){    System.out.println(driver.findElement(By.xpath("//input[@class='default_shipping_address']/following-sibling::span[1]")).getText());}

If that class is not unique, maybe the DIV's className selectCard_left is?

if(driver.findElement(By.className("selectCard_left"))){    System.out.println(driver.findElement(By.xpath("//div[@class='selectCard_left']/span[1]")).getText());}

If none of the classNames are unique, a complete xpath expression is required. If you still are unable to get that text, I refer to reading up on how to use xpath: http://www.w3schools.com/XPath/xpath_syntax.asp

I hope that you find this information useful.
