[Golang] XML Parsing Example (3)

February 21, 2015

In this exmaple, we will parse a div element with a span child element, <span>SpanText</span>:

example-3.xml | repository | view raw 

<?xml version="1.0" encoding="UTF-8"?><div><span>SpanText</span></div>

Just as we declare a struct for parent div element, we also declare a struct for the child span element, and add a struct field of the span struct to the div struct.

Run code on Go Playground

parse-3.go | repository | view raw 

package main

import (
	"io/ioutil"
	"encoding/xml"
	"fmt"
)

type div struct {
	XMLName		xml.Name	`xml:"div"`
	ChildSpan	span
}

type span struct {
	XMLName		xml.Name	`xml:"span"`
	Text		string		`xml:",chardata"`
}

func main() {
	d := div{}
	xmlContent, _ := ioutil.ReadFile("example-3.xml")
	err := xml.Unmarshal(xmlContent, &d)
	if err != nil { panic(err) }
	fmt.Println("ChildSpan:", d.ChildSpan)
}

The output result:

ChildSpan: {{ span} SpanText}

Tested on: Ubuntu Linux 14.10, Go 1.4.
