Its possible to make Lines field a string type and make split after xml import, but it doesn't seems to be very elegant solution. Is

Printf ( "%T\n" , i ) fmt . Printf ( "%T\n" , & i ) json . Unmarshal ( j , & i ) fmt . Printf ( "%T\n" , i ) } type Test struct { Foo string } func main () { test ( Test {}) } Which outputs: main .
