如何在go中解组xml枚举属性？

package main

import (
    "encoding/xml"
    "fmt"
)

type Person struct {
    XMLName xml.Name `xml:"person"`
    Name    string   `xml:"name"`
    Gender  Gender   `xml:"gender"`
}

type Gender string

const (
    Male   Gender = "male"
    Female Gender = "female"
)

func main() {
    xmlData := `
        <person>
            <name>John</name>
            <gender>male</gender>
        </person>
    `

    var p Person
    err := xml.Unmarshal([]byte(xmlData), &p)
    if err != nil {
        fmt.Println("解析XML失败:", err)
        return
    }

    fmt.Println("姓名:", p.Name)
    fmt.Println("性别:", p.Gender)
}

姓名: John
性别: male
