search and replace regex for JSON string -

I have a JSON string of some objects.

I

• remove all keys,
• 'alpha' at any child level or on any child

  Replace every key with the condition that if 'A' starts with and ends with 'z'.

  For example:

  I have json string:

    "{" A ": {" b ": 4}," b "{" C ": {" d ":" e "," awefz ": {" l ":" c "}}}," c ": {" abcz ":" here "}}"  
    "{" a ": {" b "4", "b": {"c" : "{" A:: {"d": "e"}}, "c": {}} "  
   after implementing regex 2):" {"D": "E", "alpha": {"L": "c"}}, "c": {"alpha": " Here I am just looking for those reges.  
   I only need JSONString and regex (to search) as input .  
   I'm the key I do not want to loop through the recursive L. O. By the levels I just want to use regex on the JSON string.  
   Is there any solution?   < P> 
   
    regex 1:   
   ,? \ S * "a [^" ] * Z "\ s *: [^}] +   
   Replace with:  ''   
   Output:  {"A": {"b": 4}, "b": {"c": {"d": "e"}}}, "c": {}} "< / Code>  
   Demo:  
    regex 2:   
    a [^ "* * z  Replace with  
  :  alpha   
   output:  
    "{" a ": {" b ": 4 }, "b": {"c": {"D": "e", "alpha": {"l": "c"}}}, "c": {"alpha": "here"}} "
