9_Regular Expressions

Regular expressions-

Sometimes in HTML, the developer defines more than one class name ( that’s class input has more than one name

Here  the email or phone number in Gmail has the following HTML STRUCTURE

<input type="email" class="whsOnd zHQkBf" jsname="YPqjbf" autocomplete="username" spellcheck="false" tabindex="0" aria-label="Email or phone" name="identifier" autocapitalize="none" id="identified" dir="ltr" data-initial-dir="ltr" data-initial-value="" badinput="false" aria-invalid="true">

 You can see that the input class attribute is composed of more than one name - whsOnd zHQkBf

In order to frame the CSS path for this, we can use regular expression as –

* à  perform a partial match with the class attribute value. The CSS value shall be input[class*= whsOnd]

This means the subtext whsOnd is present in the actual text whsOnd zHQkBf

 ^ à perform a match with the class. The CSS value shall be input[class^= ‘whsOnd’]. This means the actual text whsOnd zHQkBf starts with the subtext whsOnd.

$ àperform a match with the class. The CSS value shall be input[class$=’zHQkBf’]. This means the actual text whsOnd zHQkBf ends with the subtext zHQkBf.

For each of these three regular expression usages, the code will look as –

Using *

driver.get("https://accounts.google.com/");

driver.findElement(By.cssSelector("input[class*= whsOnd]")).sendKeys("admin");

 

Using ^

driver.get("https://accounts.google.com/");

driver.findElement(By.cssSelector("input[class^='whsOnd']")).sendKeys("admin");
