如何在golang中获取使用reflect.New（）创建的对象的指针

I have a function which must accept object type. Then it must unmarshal XML to an object of a given type.

Getting object type with reflect:

objType := reflect.TypeOf(CustomObjectType{})
UnmarshalWorker(objType)

Unmarshal function:

func UnmarshalFeedGeneric (data []byte,objType reflect.Type) {
    unm := reflect.New(objType)
    err := xml.Unmarshal(data, unm.Interface())
}

And 'unm' always return nil value.

fmt.Println(unm)
fmt.Println(unm.Elem())
fmt.Println(unm.Interface())

Output:

<*main.CustomObjectType Value>
<main.CustomObjectType Value>
&{ <nil>   0}
