# 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}}`
