Parse XML file in Unity C#

I have a little problem with parsing XML file to object in C#. Whole project is in Unity3D. So I have this XML file:

 <Questions>
     <Question>
         <questionText>What is this?</questionText>
         <answer>blablabla</answer>
     </Question>
 </Questions>

And this is my parsing class:

 using UnityEngine;
 using System.Collections.Generic;
 using System.Xml;
 using System.Xml.Serialization;
 using System.IO;
 using System;
 
 public struct Montage {
     [XmlElement("questionText")]
     public string questionText;
 
     [XmlElement("answer")]
     public string answer;
 }
 
 [XmlRoot("Questions"), XmlType("Questions")]
 public class ConfigScene {
 
     [XmlArray("Questions")]
     [XmlArrayItem("Question")]
     public List<Montage> questions = new List<Montage> ();
 
     public static ConfigScene Load(string path) {
         try {
             XmlSerializer serializer = new XmlSerializer (typeof(ConfigScene));
             using(FileStream stream = new FileStream(path, FileMode.Open)) {
                  return serializer.Deserialize(stream) as ConfigScene;
             }
         } catch (Exception e) {
              UnityEngine.Debug.LogError ("Exception loading config file: " + e);
 
              return null;
         }
     }
 }

I'm calling this "Load" method in camera Object in Start() method:

 void Start () {
     confScene = ConfigScene.Load(Path.Combine(Application.dataPath, "Config/config2.xml"));
     foreach(Montage o in confScene.questions) {
         Debug.Log (o.questionText);
     }
 }

The problem is that my questions list is empty and I didn't get any provided data into it. Do I make something wrong? Maybe someone made it before and know what is wrong with this code?
