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 main
import (
"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 main
import (
"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))
}
