You need to export your struct fields as per https://golang.org/pkg/encoding/xml/#Unmarshal

Because Unmarshal uses the reflect package, it can only assign to exported (upper case) fields. Unmarshal uses a case-sensitive comparison to match XML element names to tag values and struct field names.

e.g.

type Proto struct {
    XMLName xml.Name `xml:"field"`
    Name      string `xml:"name,attr"`
    Shownameg string `xml:"showname,attr"`
    Fields []Field
}
