+# 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}}`
