XML Unmarshaling attribute & inner value

Question

When attempting to parse some XML, in the below example.

How can the attribute 'id' for Owner be referenced and parsed?

import (
    "encoding/xml"
    "fmt"
)

var Sample = `<?xml version="1.0"?>                                                                                                                                                                      
<items>                                                                                                                                                                                     
  <item id="10">

To reference the attribute 'id' for Owner: items.Items[0].Owner.Id

fmt.Println("Owner Id: ", items.Items[0].Owner.Id)
