英文:
Go: Marshall array/slice of different types to XML
问题
我有一个结构体：
type Response struct {Verbs []interface{}}
还有一些其他的动词结构体，比如：
type Verb1 struct {Field1 string...}type Verb2 struct {Field2 int...}
如何从对象
&Response{Verbs: []interface{}{Verb1{}, Verb2{}, Verb1{}}}
生成如下的 XML：
<Response><Verb1>...</Verb1><Verb2>...</Verb2><Verb1>...</Verb1></Response>
我尝试使用 encoding/xml，但它也生成了 Verbs 元素，如下所示：
<Response><Verbs><Verb1>...</Verb1><Verb2>...</Verb2><Verb1>...</Verb1></Verbs></Response>
如何避免生成 <Verbs>？
英文:
I have a struct
type Response struct {Verbs []interface{}}
and some another structs of verbs like
type Verb1 struct{Field1 string...}type Verb2 struct{Field2 int...}
How to from object
&Response{Verbs: []interface{}{Verb1{}, Verb2{}, Verb1{}}}
to get XML like
<Response><Verb1>...</Verb1><Verb2>...</Verb2><Verb1>...</Verb1></Response>
?
I tried to use encoding/xml but it generates element Verbs too like
<Response><Verbs><Verb1>...</Verb1><Verb2>...</Verb2><Verb1>...</Verb1></Verbs></Response>
How to avoid generations of <Verbs>?

你需要明确命名Verb类型。
package mainimport ("encoding/xml""fmt")type Root struct {Container []interface{}}type A struct {XMLName xml.Name `xml:"A"`Value string `xml:",chardata"`}type B struct {XMLName xml.Name `xml:"B"`Value string `xml:",chardata"`}func main() {r := Root{Container: []interface{}{A{Value: "a"},B{Value: "b"},},}text, _ := xml.Marshal(r)fmt.Println(string(text))}
英文:
You need to name Verb types explicitly.
package mainimport ("encoding/xml""fmt")type Root struct {Container []interface{}}type A struct {XMLName xml.Name `xml:"A"`Value string `xml:",chardata"`}type B struct {XMLName xml.Name `xml:"B"`Value string `xml:",chardata"`}func main() {r := Root{Container: []interface{}{A{Value: "a"},B{Value: "b"},},}text, _ := xml.Marshal(r)fmt.Println(string(text))}
