So you only wanted the value when id=2 not id=1 or 3? Because if you wanted it for any id the accepted answer doesn't work.

(?:(id = d+)[^{}]*?(value="[^"rn]*")|(value="[^"rn]*")[^{}]*?(id = d+))

will match all pairs id/value

Explanation:

(?:

    (id = d+)              # group 1, id

    [^{}]*?                 # 0 or more any character but curly braces

    (value="[^"rn]*")     # group 2, value

  |                         # OR

    (value="[^"rn]*")     # group 3, value

    [^{}]*?                 # 0 or more any character but curly braces

    (id = d+)              # group 4, id

)

i think you should include the braces in your negative lookahead to at least avoid this: regex101.com/r/YWooji/2
