Question: I have a search string that is getting passed

>

I want to filter out all sub strings surrounded by double quotes("").
In above sample Output should contain: 

> 
> "a+b","C","d+e"
>

Is there a way to do this without looping?

Also I then need to extract a string without above values to do further processing

Any suggestions on how to do this with minimal performance impact?

Thank you in advance for all your comments and suggestions
