Добрый день, есть ajax запрос:

$.ajax({
                                                                type: "POST",
                                                                url: "http://geotest/ajax.php",
                                                                data: { centerDist:centerDistance,pointDist:pointsDistance },
                                                                success: function(msg){

                                                                }
                                                            });

который посылает некие данные на обработку в php, после обработки они возвращаются вот в таком виде:

{"C":[{"path":["C","C3","C8","C2","C12","C"],"point":[["48.5515","29.5915"],["45.729","29.7453"],["48.0188","31.0637"],["47.6686","32.404"]]},{"path":["C","C11","C"],"point":{"4":["49.3284","31.1077"]}}],
"D":[{"path":["D","D7","D5","D4","D14","D"],"point":[["48.039","38.2796"],["47.1016","35.2604"],["48.6972","35.7438"],["50.0099","37.1602"]]},{"path":["D","D10","D"],"point":{"4":["50.0695","33.7004"]}}],
"A":[{"path":["A","A0","A13","A1","A"],"point":[["51.5378","33.5307"],["50.3561","32.1842"],["50.2153","29.5036"]]}],
"B":[{"path":["B","B9","B6","B"],"point":[["50.8827","25.3508"],["50.039","25.2796"]]}]}

Подскажите как можно вытащить все значения поля "point" ?
