14 var jsonDocument map[string]interface{}
15 json.Unmarshal([]byte(jsonText), &jsonDocument)
16
17 //create a JSON pointer
18 pointerString := "/occupation/title"
19 pointer, _ := NewJsonPointer(pointerString)
20
21 //SET a new value for the "title" in the document
22 pointer.Set(jsonDocument, "Supreme Leader of Westeros")
23
24 //GET the new "title" from the document
25 title, _, _ := pointer.Get(jsonDocument)
26 fmt.Println(title) //outputs "Supreme Leader of Westeros"
27
28 //DELETE the "heir" from the document
29 deletePointer := NewJsonPointer("/occupation/heir")
30 deletePointer.Delete(jsonDocument)
31
32 b, _ := json.Marshal(jsonDocument)
33 fmt.Println(string(b))
34 //outputs `{"name":"Bobby B","occupation":{"title":"Supreme Leader of Westeros","years":15}}`
