json.path.set() Function
• Introduced in version 1.5.5
Change an element in a nested JSON Array. Additional information on how to specify the path is available here.
Usage
json.path.add(json, path, value)
Parameters
json
- The json element in which the JSON Array is nested.path
- The path to the element in the JSON Array.value
- The value to change.
Examples
Suppose we have the following nested json:
[h:troll = json.set("{}", "name", "Troll", "HP", 75, "Attacks", json.append("Claw", "Bite"))]
[h:orc = json.set("{}", "name", "Orc", "HP", 13, "Attacks", json.append("Sword", "Punch"))]
[h:monsters = json.set("{}", "Troll", troll, "Orc", orc)]
To replace the Punch to an Axe, we can run
[monsters = json.path.set(monsters, "Orc.Attacks.[1]", "Axe")]
To change all "Sword" attacks to "Greatsword", we can run
[monsters = json.path.set(monsters, "*.Attacks[?(@ == 'Sword')]", "Great Sword")]
