Unmarshal JSON and XML into the same Go structure slice with proper data type

I’m consuming a REST service which gives various lists in both JSON and XML formats, something similar to these ones:

[  
   {  
      "id":803267,
      "name":"Paris, Ile-de-France, France",
      "region":"Ile-de-France",
      "country":"France",
      "is_day":1,
      "localtime":"2018-05-12 12:53"
   },
   {  
      "id":760995,
      "name":"Batignolles, Ile-de-France, France",
      "region":"Ile-de-France",
      "country":"France",
      "is_day":0,
      "localtime":"2018-05-12"
   }
]
<?xml version="1.0" encoding="UTF-8"?>
<root>
   <geo>
      <id>803267</id>
      <name>Paris, Ile-de-France, France</name>
      <region>Ile-de-France</region>
      <country>France</country>
      <is_day>1</is_day>
     <localtime>2018-05-12 12:53</localtime>
   </geo>
   <geo>
      <id>760995</id>
      <name>Batignolles, Ile-de-France, France</name>
      <region>Ile-de-France</region>
      <country>France</country>
      <is_day>0</is_day>
      <localtime>2018-05-12</localtime>
   </geo>
</root>

And I wanted to get them into a slice of this type of structures:

type Locations []Location

type Location struct {
   ID        int      `json:"id" xml:"id"`
   Name      string   `json:"name" xml:"name"`
   Region    string   `json:"region" xml:"region"`
   Country   string   `json:"country" xml:"country"`
   IsDay     int      `json:"is_day" xml:"is_day"`
   LocalTime string   `json:"localtime" xml:"localtime"`
}

It’s straight forward for JSON: Continue reading Unmarshal JSON and XML into the same Go structure slice with proper data type
