How to modify null value/two double quotes that contain nothing in xml with Powershell?

I need to modify web.config file which I am reading as xml and the line i need to change is this:

<add key="My.Unique.Repository" value="" />

as you can see, there is nothing in value=" " just the double quotes.

I have no script written for this, I am trying to find out how to do it in the simplest way before I attempt to compile code

P.S. I have zero powershell experience, kindly respond in simple terms, thank you
