Question

I have a problem to create a regular expression. I have a string like this (a simple json response froma webserver):

{
    "key1":valueInt1,
    "key2":valueInt2,
    [...]
    "specialKey":"",
    "subtitle":"Every kind of character, like char, num or punct",
    "key3":"Useful line",
}

What I want is to delete the keys “specialKey” and its value and “subtitle” with its value. Both of them can be empty (like specialKey in my example).

I have tried something like that:

(\"subtitle\"\:\")([:punct:]*[:space:]*[:word:]*)*(\",)

Without success. The error is the part ([:punct:][:space:][:word:]) to match my random sentence.

Thanks for your help!

Answer 1

Character classes are usually only used within bracket expressions. If you change what you have into:

(\"subtitle\"\:\")([[:punct:][:space:][:word:]]*)*(\",)

It should work.
