How to use regular expressions in a CSS locator?

Rest AssuredDynamic ProgrammingProgramming

We can use regular expressions in a CSS locator. We can identify elements by matching their attributes partially with the help of regular expressions. In CSS, there are multiple methods to achieve this. They are listed below −

  • Using the wild character *. This means the string contains our given text.

    Syntax− driver.find_element_by_css_selector("input[name*='sel']")

    It will search the input tag which contains the 'name' attribute containing 'sel' text.

  • Using the wild character ^. This means the string starts with our given text.

    Syntax− driver.find_element_by_css_selector("input[name^='Tut']")

    It will search the input tag which contains the 'name' attribute starting with 'Tut' text.

  • Using the wild character $. This means the string ends with our given text.

    Syntax− driver.find_element_by_css_selector("input[name$='nium']")

    It will search the input tag which contains the 'name' attribute ending with 'nium' text.
