我需要生成這樣的 XML 文件： <package> <dc:contributor id="creator1">John Doe</dc:contributor> <meta refines="creator1" property="role" scheme="marc:relators">aut</meta> <meta refines="creator1" property="role" scheme="onix:codelist17">A01</meta> <meta refines="creator1" property="file-as">Doe, John</meta> <meta refines="creator1" property="diplay-seq">1</meta> <dc:contributor id="reviewer1">Mary Poppins</dc:contributor> <meta refines="reviewer1" property="role" scheme="marc:relators">rev</meta> <meta refines="reviewer1" property="file-as">Poppins, Mary</meta> <meta refines="reviewer1" property="diplay-seq">1</meta> <dc:contributor id="translator1">Alfred Weasley</dc:contributor> <meta refines="translator1" property="role" scheme="marc:relators">trl</meta> <meta refines="translator1" property="role" scheme="onix:codelist17">B06</meta> <meta refines="translator1" property="file-as">Weasley, Alfred</meta> <meta refines="translator1" property="diplay-seq">1</meta> </package>排序在這里很重要。我使用這種結構：type Pack struct { XMLName struct{} `xml:"package"` People []PersonWrapper `xml:""` // <-- is this the problem?}type Person struct { Id string `xml:"id,attr"` Name string `xml:"-"` Surname string `xml:"-"` FullName string `xml:",innerxml"`}type Meta struct { Refines string `xml:"refines,attr"` Property string `xml:"property,attr"` Scheme string `xml:"scheme,attr,omitempty"` Value string `xml:",innerxml"`}type PersonWrapper struct { Person Person `xml:"dc:contributor"` Metas []Meta `xml:"meta"`}如何擺脫<People/>外部標簽？我試圖將內部結構包裝到更高級別的其他結構中，但無法達到所需的結構。

您可以實現xml.Marshaler接口PersonWrapper（并將 xmlnames 添加到嵌套結構中）。
type Pack struct {
XMLName struct{} `xml:"package"`
People []PersonWrapper
}
type Person struct {
XMLName xml.Name `xml:"dc:contributor"`
Id string `xml:"id,attr"`
Name string `xml:"-"`
Surname string `xml:"-"`
FullName string `xml:",innerxml"`
}
type Meta struct {
XMLName xml.Name `xml:"meta"`
Refines string `xml:"refines,attr"`
Property string `xml:"property,attr"`
Scheme string `xml:"scheme,attr,omitempty"`
Value string `xml:",innerxml"`
}
type PersonWrapper struct {
Person Person `xml:"dc:contributor"`
Metas []Meta `xml:"meta"`
}
func (pw PersonWrapper) MarshalXML(e *xml.Encoder, start xml.StartElement) error {
if err := e.Encode(pw.Person); err != nil {
return err
}
if err := e.Encode(pw.Metas); err != nil {
return err
}
return nil
}
