xml文件生成

参考这篇文章https://segmentfault.com/a/1190000016932102

例子

package main

import (
    "encoding/xml"
    "fmt"
    "os"
)

type Server struct {
    XMLName    xml.Name `xml:"server"`
    ServerName string   `xml:"serverName"`
    ServerIP   string   `xml:"serverIP"`
}

type XMLServers struct {
    XMLName     xml.Name `xml:"servers"`
    Version     string   `xml:"version,attr"`
    Servers     []Server `xml:"server"`
    Description string   `xml:",innerxml"`
}

func main() {
    v := &XMLServers{
        Version: "1",
    }

    v.Servers = append(v.Servers, Server{
        ServerName: "Shanghai_VPN",
        ServerIP:   "127.0.0.1",
    })

    v.Servers = append(v.Servers, Server{
        ServerName: "Beijing_VPN",
        ServerIP:   "127.0.0.2",
    })

    output, err := xml.MarshalIndent(v, "", "    ")
    if err != nil {
        fmt.Println(err)
        return
    }

    os.Stdout.Write([]byte(xml.Header))
    os.Stdout.Write(output)
}

生成的内容如下

<?xml version="1.0" encoding="UTF-8"?>
<servers version="1">
    <server>
        <serverName>Shanghai_VPN</serverName>
        <serverIP>127.0.0.1</serverIP>
    </server>
    <server>
        <serverName>Beijing_VPN</serverName>
        <serverIP>127.0.0.2</serverIP>
    </server>
</servers>
