How to range over []interface{}

I have this interface{}, resulting from a json unmarshal.
(interface {}) (len=2 cap=2) {
(map[string]interface {}) (len=2) {
(string) (len=6) "@value": (string) (len=10) "Repository",
(string) (len=9) "@language": (string) (len=2) "en"
},
(map[string]interface {}) (len=2) {
(string) (len=6) "@value": (string) (len=7) "Ystorfa",
(string) (len=9) "@language": (string) (len=5) "cy-GB"
}
}
How can I range over the slice? If I simply try: for _, c := range Container {
I got the error:
cannot range over Container (type interface {})

You have a slice wrapped in aninterface{}value. First do a type assertion to obtain the slice value, which you can rage over afterwards. E.g.for _, c := range Container.(interface{}). Note: error check (if it is notnilor if it truly is a slice) is omitted.
