我要评论本文实例讲述了golang解析xml的方法。分享给大家供大家参考，具体如下：
golang解析xml真是好用,特别是struct属性的tag让程序简单了许多,其他变成语言需要特殊类型的在golang里直接使用tag舒服
xml文件点击此处。
完整示例代码：
复制代码 代码如下:
package main
import (
"os"
"encoding/xml"
// "encoding/json"
"io/ioutil"
"fmt"
)
type location struct {
countryregion []countryregion
}
type countryregion struct {
name string `xml:",attr"`
code string `xml:",attr"`
state []state
}
type state struct {
name string `xml:",attr"`
code string `xml:",attr"`
city []city
}
type city struct {
name string `xml:",attr"`
code string `xml:",attr"`
region []region
}
type region struct {
name string `xml:",attr"`
code string `xml:",attr"`
}
func main() {
f, err := os.open("loclist.xml")
if err != nil {
panic(err)
}
data, err := ioutil.readall(f)
if err != nil {
panic(err)
}
// v := make(map[string]interface{})
var v location
err = xml.unmarshal(data, &v)
if err != nil {
panic(err)
}
// fmt.printf("%#v\n", v)
// table
for _, countryregion := range v.countryregion {
// fmt.printf("%s,%s\n", countryregion.code, countryregion.name)
if len(countryregion.state) == 0 {
continue
}
for _, state := range countryregion.state {
// fmt.printf("%s,%s,%s\n", countryregion.code, state.code, state.name)
if len(state.city) == 0 {
continue
}
for _, city := range state.city {
// fmt.printf("%s,%s,%s,%s\n", countryregion.code, state.code, city.code, city.name)
if len(city.region) == 0 {
continue
}
for _, region := range city.region {
fmt.printf("%s,%s,%s,%s,%s\n", countryregion.code, state.code, city.code, region.code, region.name)
}
}
}
}
// // json
// js, err := json.marshal(&v.countryregion[0])
// if err != nil {
// panic(err)
// }
// fmt.printf("%s\n", js)
}
import (
"os"
"encoding/xml"
// "encoding/json"
"io/ioutil"
"fmt"
)
type location struct {
countryregion []countryregion
}
type countryregion struct {
name string `xml:",attr"`
code string `xml:",attr"`
state []state
}
type state struct {
name string `xml:",attr"`
code string `xml:",attr"`
city []city
}
type city struct {
name string `xml:",attr"`
code string `xml:",attr"`
region []region
}
type region struct {
name string `xml:",attr"`
code string `xml:",attr"`
}
func main() {
f, err := os.open("loclist.xml")
if err != nil {
panic(err)
}
data, err := ioutil.readall(f)
if err != nil {
panic(err)
}
// v := make(map[string]interface{})
var v location
err = xml.unmarshal(data, &v)
if err != nil {
panic(err)
}
// fmt.printf("%#v\n", v)
// table
for _, countryregion := range v.countryregion {
// fmt.printf("%s,%s\n", countryregion.code, countryregion.name)
if len(countryregion.state) == 0 {
continue
}
for _, state := range countryregion.state {
// fmt.printf("%s,%s,%s\n", countryregion.code, state.code, state.name)
if len(state.city) == 0 {
continue
}
for _, city := range state.city {
// fmt.printf("%s,%s,%s,%s\n", countryregion.code, state.code, city.code, city.name)
if len(city.region) == 0 {
continue
}
for _, region := range city.region {
fmt.printf("%s,%s,%s,%s,%s\n", countryregion.code, state.code, city.code, region.code, region.name)
}
}
}
}
// // json
// js, err := json.marshal(&v.countryregion[0])
// if err != nil {
// panic(err)
// }
// fmt.printf("%s\n", js)
}
希望本文所述对大家go语言程序设计有所帮助。
