Hi,
At work I have 3 different xml files I need to parse (different fields
each), Because going from the xml bytes into a struct is pretty much the
same
for all 3 types, I thought I could do something like
var payload interface{}
if kind == "A" {
paylaod = TypeA{}
}
if kind == "B" {
paylaod = TypeB{}
}
if kind == "C" {
paylaod = TypeC{}
}
....
xml.Unmarshal([]byte(file), &payload)
but this fails. It doesn't give me an error, but Unmarshal doesn't
recognize the payload variable as the right (new) type.
I created a very simple snippet here
https://play.golang.org/p/QvVbM--Zdt
produces:
gen is type: main.X //<== see how the type is correct here
xml gen is {One:}
json gen is map[One:uno]
gen is type: main.X //<== here I declared the variable with the right type
and Unmarshal works
xml gen is {One:uno}
json gen is {One:uno}
Hope this is enough information.
Thanks
Diego
