xml格式化写入文件

参考xml文件地址：http://cloudprint.cainiao.com/template/standard/101

代码：

package main
 
import (
    "encoding/xml"
    "fmt"
    "os"
    "time"
)
 
type xmldas struct {
    XMLName           xml.Name       `xml:"page"`
    Xmlns             string         `xml:"xmlns,attr"`
    XmlnsXsi          string         `xml:"xmlns:xsi,attr"`
    XsiSchemaLocation string      `xml:"xsi:schemaLocation,attr"`
    XmlnsEditor       string        `xml:"xmlns:editor,attr"`
    Width             string         `xml:"width,attr"`
    Height            string        `xml:"height,attr"`
    Auth              xmlAuth        `xml:"auth"`
}
 
type xmlAuth struct {
    Name string `xml:name`
    Age  int `xml:age`
}
 
func main() {
    v := xmldas{Xmlns:"http://cloudprint.cainiao.com/print", XmlnsXsi:"http://www.w3.org/2001/XMLSchema-instance", XsiSchemaLocation:"http://cloudprint.cainiao.com/print http://cloudprint-docs-resource.oss-cn-shanghai.aliyuncs.com/lpml_schema.xsd", XmlnsEditor:"http://cloudprint.cainiao.com/schema/editor", Width:"", Height:"" }
    v.Auth = xmlAuth{Name:"ha666", Age:}
    output, err := xml.MarshalIndent(v, "", "\t")
    if err != nil {
        fmt.Printf("error: %v\n", err)
    }
    filename := time.Now().Format("2006-01-02-15-04-05")
    userFile := filename + ".xml"
    fout, err := os.Create(userFile)
    defer fout.Close()
    if err != nil {
        fmt.Println(userFile, err)
        return
    }
    fout.Write([]byte(xml.Header))
    fout.Write(output)
    fout.Close()
}

生成的xml：

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://cloudprint.cainiao.com/print" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://cloudprint.cainiao.com/print http://cloudprint-docs-resource.oss-cn-shanghai.aliyuncs.com/lpml_schema.xsd" xmlns:editor="http://cloudprint.cainiao.com/schema/editor" width="" height="">
    <auth>
        <Name>ha666</Name>
        <Age></Age>
    </auth>
</page>
