go语言学习 ---struct 对象的序列化和反序列化（xml）

实例1：

//main
package main

import (
	"encoding/xml"
	"fmt"
)

type person struct {
	Name string
	Age  int
}

func main() {
	p := person{Name: "sary", Age: 20}

	if data, err := xml.MarshalIndent(p, "", " "); err != nil {
		fmt.Println(err)
		return
	} else {
		fmt.Println(string(data))
	}

}

　　输出：

D:/Go/bin/go.exe build [D:/GOPATH/src/study.go]

Success: process exited with code 0.

D:/GOPATH/src/study.go/study.go.exe [D:/GOPATH/src/study.go]

<person>

<Name>sary</Name>

<Age>20</Age>

</person>

Success: process exited with code 0.

实例2

//main

package main

import (

	"encoding/xml"

	"fmt"

)

type person struct {

	Name string

	Age  int

}

func main() {

	p := person{Name: "sary", Age: 20}

	var data []byte

	var err error

	if data, err = xml.MarshalIndent(p, "#", " "); err != nil {

		fmt.Println(err)

		return

	}

	fmt.Println(string(data))

	p2 := new(person)

	if err = xml.Unmarshal(data, p2); err != nil {

		fmt.Println(err)

		return

	}

	fmt.Println(p2)

}

　　输出：

D:/Go/bin/go.exe build [D:/GOPATH/src/study.go]

Success: process exited with code 0.

D:/GOPATH/src/study.go/study.go.exe [D:/GOPATH/src/study.go]

#<person>

# <Name>sary</Name>

# <Age>20</Age>

#</person>

&{sary 20}

Success: process exited with code 0.

实例3：（设置标签属性）

//main
package main

import (
	"encoding/xml"
	"fmt"
)

type person struct {
	Name string `xml:"Name,attr"`
	Age  int    `xml:"Age,attr"`
}

func main() {
	p := person{Name: "sary", Age: 20}

	var data []byte
	var err error

	if data, err = xml.MarshalIndent(p, "#", " "); err != nil {
		fmt.Println(err)
		return
	}

	fmt.Println(string(data))

	p2 := new(person)
	if err = xml.Unmarshal(data, p2); err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(p2)

}

　　输出：

Success: process exited with code 0.
