How do I spawn a random unit from my XML file?

Hey guys,

What I'm trying to do is:

Start the game, when the game starts you spawn 4 random champions from a database of hundreds onto a panel as it's a 2D game, and the champions will be more of a card form.

What I'm having problems with is how do I spawn 4 random champions with attributes from an XML file? I don't understand how to link the scripts to the xml.

Here's what I have so far:

This is the xml (the full list of champions is far longer):

 <?xml version="1.0" encoding="UTF-8"?>
 <ChampionCollection>
   <Champions>
     <Champion Name="Bob">
       <HP>5</HP>
       <MP>5</MP>
       <Attack>5</Attack>
       <Armor>2</Armor>
     </Champion>
     <Champion Name="Alex">
       <HP>10</HP>
       <MP>5</MP>
       <Attack>4</Attack>
       <Armor>1</Armor>
     </Champion>
     <Champion Name="Jess">
       <HP>20</HP>
       <MP>5</MP>
       <Attack>5</Attack>
       <Armor>0</Armor>
     </Champion>
   </Champions>
   </ChampionCollection>

The XmlSerializer script:

 using UnityEngine;
 using System.Collections;
 using System.Xml.Serialization;
 using System.IO;
 using System.Collections.Generic;
 
 [XmlRoot("ChampionCollection")]
 public class ChampionContainer {
 
     [XmlArray("Champions")]
     [XmlArrayItem("Champion")]
     public List<Champion> champions = new List<Champion>();
 
     public static ChampionContainer Load(string path)
     {
         TextAsset _xml = Resources.Load<TextAsset>(path);
 
         XmlSerializer serializer = new XmlSerializer(typeof(ChampionContainer));
 
         StringReader reader = new StringReader(_xml.text);
 
         ChampionContainer champions = serializer.Deserialize(reader) as ChampionContainer;
 
         reader.Close();
 
         return champions;
     }
 }

and another:

 using UnityEngine;
 using System.Collections;
 using System.Xml;
 using System.Xml.Serialization;
 
 public class Champion {
 
     [XmlAttribute("Name")]
     public string Name;
 
     [XmlAttribute("HP")]
     public float HP;
 
     [XmlAttribute("MP")]
     public float MP;
 
     [XmlAttribute("Attack")]
     public float Attack;
 
     [XmlAttribute("Armor")]
     public float Armor;
 }

Here's the spawn script:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 
 public class SpawnScript : MonoBehaviour
 {
 
     public GameObject[] obj;
 
     // Use this for initialization
     void Start()
     {
         Spawn();
         Spawn();
         Spawn();
         Spawn();
     }
 
     void Spawn()
     {
         GameObject newCard = (GameObject)Instantiate
             (obj[Random.Range(0, obj.GetLength(0))], transform.position, Quaternion.identity);
         newCard.transform.parent = transform;
     }
 }

I'm not sure how I should really go about this, currently I have a prefab instantiated and I want to the prefab to pull from the XML, but I have a feeling that's not how it should be done, So I'm down for any suggestions to change it up. Heads up this is my 1st project so all I really know is basic code and what I've learned from watching a bunch of tutorials.

Any help would be greatly appreciated, I've been stuck on this part for a few weeks now and just really need some help so I can finally move on.
