我正在尝试实现以下XML输出
<?xml version="1.0" encoding="UTF-8"?>
<CreateHostedZoneRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12/">
   <Name>DNS domain name</Name>
   <CallerReference>unique description</CallerReference>
   <HostedZoneConfig>
      <Comment>optional comment</Comment>
   </HostedZoneConfig>
</CreateHostedZoneRequest>下面的输出XML非常接近,但是我无法将其编码到CreateHostedZoneRequest中
package main
import "fmt"
import "encoding/xml"
type ZoneRequest struct {
  Name            string
  CallerReference string
  Comment         string `xml:"HostedZoneConfig>Comment"`
}
var zoneRequest = ZoneRequest{
  Name:            "DNS domain name",
  CallerReference: "unique description",
  Comment:         "optional comment",
}
func main() {
  tmp, _ := createHostedZoneXML(zoneRequest)
  fmt.Println(tmp)
}
func createHostedZoneXML(zoneRequest ZoneRequest) (response string, err error) {
  tmp := struct {
    ZoneRequest
    XMLName struct{} `xml:"CreateHostedZoneRequest"`
  }{ZoneRequest: zoneRequest}
  byteXML, err := xml.MarshalIndent(tmp, "", `   `)
  if err != nil {
    return "", err
  }
  response = xml.Header + string(byteXML)
  return
}http://play.golang.org/p/pyK76VPD5-
如何将xmlns编码到CreateHostedZoneRequest中?

您可以这样做,这可能不是最优雅的解决方案,但似乎有效。

type ZoneRequest struct {
    Name            string
    CallerReference string
    Comment         string `xml:"HostedZoneConfig>Comment"`
    Xmlns           string `xml:"xmlns,attr"`
}
var zoneRequest = ZoneRequest{
    Name:            "DNS domain name",
    CallerReference: "unique description",
    Comment:         "optional comment",
    Xmlns:           "https://route53.amazonaws.com/doc/2012-12-12/",
}产
<?xml version="1.0" encoding="UTF-8"?>
<CreateHostedZoneRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12/">
   <Name>DNS domain name</Name>
   <CallerReference>unique description</CallerReference>
   <HostedZoneConfig>
      <Comment>optional comment</Comment>
   </HostedZoneConfig>

我也有类似的问题。解组方法(http://golang.org/pkg/encoding/xml/#Unmarshal)的文档有:
如果XMLName字段具有表单" name“或”命名空间-URL名称“的关联标记,则XML元素必须具有给定的名称(以及(可选)名称空间),否则Un封送返回错误。
在struct标记中使用“命名空间-URL名称”:
type ZoneRequest struct {
    XMLName  xml.Name `xml:"https://route53.amazonaws.com/doc/2012-12-12/ CreateHostedZoneRequest"`
}应产生:
<CreateHostedZoneRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12/">https://stackoverflow.com/questions/16202170
