How could I add a class to a div that contains a div that contains a link that contains specific text, and name that class based on that link but with hyphens in place of spaces and all lower case? Here's specifically what I'm looking for:

1. <div class="my-div-one">
     <h2>Title of this section</h2>
     <div class="my-div-something-else"><a href="url">My Special Link</a></div>
   </div>
   
   
   
   

In the above example, I want to add the class my-special-link to my-div-one. Is that possible? How could I do that?

Thanks,
Gary
