You are welcome.
 
Yesterday, I though I did saw somewhere about 
this is classic question; that's right, it is in the
"Mastering Regular Expression" book.
 
After check, the solution on the book is just like 
what I came out, but in the book, 
they gave other one for more performance:
 
/"(?:[^\\"]+|\\.)+"/  # did you see the different? :-)
 
BTW: if you like to match empty string like "" you can
change to 
/"(?:[^\\"]+|\\.)*"/  
 
You can check the book for more information.
