Decode XML
Examples in
Go
Go offers built-in support for XML and XML-like formats with the encoding.xml package.
package main
import (
"encoding/xml"
"fmt"
)
type Plant struct {
XMLName xml.Name `xml:"plant"`
Id int `xml:"id,attr"`
Name string `xml:"name"`
Origin []string `xml:"origin"`
}
func (p Plant) String() string {
return fmt.Sprintf("Plant id=%v, name=%v, origin=%v",
p.Id, p.Name, p.Origin)
}
func main() {
coffee := &Plant{Id: 27, Name: "Coffee"}
coffee.Origin = []string{"Ethiopia", "Brazil"}
out, _ := xml.MarshalIndent(coffee, " ", " ")
fmt.Println(string(out))
fmt.Println(xml.Header + string(out))
var p Plant
if err := xml.Unmarshal(out, &p); err != nil {
panic(err)
}
fmt.Println(p)
tomato := &Plant{Id: 81, Name: "Tomato"}
tomato.Origin = []string{"Mexico", "California"}
type Nesting struct {
XMLName xml.Name `xml:"nesting"`
Plants []*Plant `xml:"parent>child>plant"`
}
nesting := &Nesting{}
nesting.Plants = []*Plant{coffee, tomato}
out, _ = xml.MarshalIndent(nesting, " ", " ")
fmt.Println(string(out))
}
