An implementation of JSON Pointer - Go language

Usage

jsonText := `{
	"name": "Bobby B",
	"occupation": {
		"title" : "King",
		"years" : 15,
		"heir" : "Joffrey B"			
	}
}`

var jsonDocument map[string]interface{}
json.Unmarshal([]byte(jsonText), &jsonDocument)

//create a JSON pointer
pointerString := "/occupation/title"
pointer, _ := NewJsonPointer(pointerString)

//SET a new value for the "title" in the document     
pointer.Set(jsonDocument, "Supreme Leader of Westeros")

//GET the new "title" from the document
title, _, _ := pointer.Get(jsonDocument)
fmt.Println(title) //outputs "Supreme Leader of Westeros"

//DELETE the "heir" from the document
deletePointer := NewJsonPointer("/occupation/heir")
