Golang encoding/xml.MarshalIndent() function example

package encoding/xml

MarshalIndent works like Marshal, but each XML element begins on a new indented line that starts with prefix and is followed by one or more copies of indent according to the nesting depth.

 package main

 import (
 "encoding/xml"
 "fmt"
 )

 type Address struct {
 City, State string
 }
 type Person struct {
 XMLName xml.Name `xml:"person"`
 Id int `xml:"id,attr"`
 FirstName string `xml:"name>first"`
 LastName  string `xml:"name>last"`
 Age int `xml:"age"`
 Height float32  `xml:"height,omitempty"`
 Married bool
 Address
 Comment string `xml:",comment"`
 }

 func main() {
 v := &Person{Id: 13, FirstName: "John", LastName: "Doe", Age: 42}
 v.Comment = " Need more details. "
 v.Address = Address{"Hanga Roa", "Easter Island"}

 output, err := xml.MarshalIndent(v, " ", " ")
 if err != nil {
 fmt.Printf("error: %v\n", err)
 }

 fmt.Println(string(output))
 }
