| # gojsonpointer
 | |
| 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")
 | |
|     deletePointer.Delete(jsonDocument)
 | |
|     
 | |
|     b, _ := json.Marshal(jsonDocument)
 | |
|     fmt.Println(string(b))
 | |
|     //outputs `{"name":"Bobby B","occupation":{"title":"Supreme Leader of Westeros","years":15}}`
