Reading an XML file

In this subsection, you will learn how to read an XML file from disk and store it into a Go structure. The name of the program is readXML.go and it will be presented in three parts. The first part of readXML.go is as follows:

package main 
 
import ( 
    "encoding/xml" 
    "fmt" 
    "os" 
) 
 
type Record struct { 
    Name    string 
    Surname string 
    Tel     []Telephone 
} 
 
type Telephone struct { 
    Mobile bool 
    Number string 
} 

The second part of readXML.go is the following:

func loadFromXML(filename string, key interface{}) error { 
    in, err := os.Open(filename) 
    if err != nil { 
        return err 
    } 
 
    decodeXML := xml.NewDecoder(in) 
    err = decodeXML.Decode(key) 
    if err != nil { 
        return err 
    } 
    in.Close() 
    return nil 
} 

The presented process is very similar to the way that ...
