How to get attributes values of element in Selenium using getAttribute Method

Using getAttribute, we can extract the value of attribute of an element in Selenium WebDriver. Extracting values of attribute of element can be helpful in a number of ways. Some of the important use of getattribute method are as follows: 

• Name of all the links or button or an object type in the Page.

• Validating if object with particular property exists in the Page.

• Extracting the href value for a button/link.

• Extracting values of element of a particular class or Id. For e.g: If error message are displayed on the page with the same class. We can get all the error messages displayed getting text attribute for all element with the common class name.

Below code explains use of getattribute in Selenium Webdriver for the above purpose.
