Sublime: replace everything between quotes

I need help with regex search and replace in Sublime to do the following.

I have HTML code with links like

 href="http://www.example.com/test=123" 
 href="http://www.example.com/test=6546" 
 href="http://www.example.com/test=3214" 

      

        
        
        
      

    

I want to replace them with empty links:

 href="" 
 href="" 
 href="" 

      

        
        
        
      

    

Please help me create a reg. ex. filter according to my case. I guess it sounds like this: "starts with Quote followed by http: // .... ends with a quote and has numbers and an" = "sign, but I'm not really sure how to write this in Reg. Ex. Path.
