本文實例講述了golang解析xml的方法。分享給大家供大家參考，具體如下：
golang解析xml真是好用,特別是struct屬性的tag讓程序簡單了許多,其他變成語言需要特殊類型的在golang里直接使用tag舒服
完整示例代碼：
復制代碼 代碼如下:
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)
}
希望本文所述對大家Go語言程序設計有所幫助。
