XML - Loading data from a xml file.

Hello everyone, in this post i pretend to show how to use a external file(xml) with texts or values in your game. I made the main script in c#. The intention is to show a conversation when you comes close to a object. Let's Work!

This is the code of the xml file which i call gamexmldata.xml:

  
    Level 1 (xml)
    Try comes close to all four objects. (xml)
    
    
    
    
    Very Good! (xml)
  
  
    Level 2 (xml)
    Try comes close to all four objects, again. (xml)
    
    
    
    
    Congratulations! (xml)
  

Ok this is our data, now we need to assign these values to variables or arrays.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.IO;
 
 
public class LoadXmlData : MonoBehaviour // the Class
{
 public TextAsset GameAsset;
 
 static string Cube_Character = "";
 static string Cylinder_Character = "";
 static string Capsule_Character = "";
 static string Sphere_Character = "";
 
 List<Dictionary<string,string>> levels = new List<Dictionary<string,string>>();
 Dictionary<string,string> obj;
 
 void Start()
 { //Timeline of the Level creator
  GetLevel();
 }
 
 public void GetLevel()
 {
  XmlDocument xmlDoc = new XmlDocument(); // xmlDoc is the new xml document.
  xmlDoc.LoadXml(GameAsset.text); // load the file.
  XmlNodeList levelsList = xmlDoc.GetElementsByTagName("level"); // array of the level nodes.
 
  foreach (XmlNode levelInfo in levelsList)
  {
   XmlNodeList levelcontent = levelInfo.ChildNodes;
   obj = new Dictionary<string,string>(); // Create a object(Dictionary) to colect the both nodes inside the level node and then put into levels[] array.
   
   foreach (XmlNode levelsItens in levelcontent) // levels itens nodes.
   {
    if(levelsItens.Name == "name")
    {
     obj.Add("name",levelsItens.InnerText); // put this in the dictionary.
    }
   
    if(levelsItens.Name == "tutorial")
    {
     obj.Add("tutorial",levelsItens.InnerText); // put this in the dictionary.
    }
   
    if(levelsItens.Name == "object")
    {
     switch(levelsItens.Attributes["name"].Value)
     {
      case "Cube": obj.Add("Cube",levelsItens.InnerText);break; // put this in the dictionary.
      case "Cylinder":obj.Add("Cylinder",levelsItens.InnerText); break; // put this in the dictionary.
      case "Capsule":obj.Add("Capsule",levelsItens.InnerText); break; // put this in the dictionary.
      case "Sphere": obj.Add("Sphere",levelsItens.InnerText);break; // put this in the dictionary.
     }
    }
   
    if(levelsItens.Name == "finaltext")
    {
     obj.Add("finaltext",levelsItens.InnerText); // put this in the dictionary.
    }
   }
   levels.Add(obj); // add whole obj dictionary in the levels[].
  }
 }
}

with this method we're created a Array with the all level node info inside and to get this values you need just do this:

string lvlName = "";
  levels[actualLevel-1].TryGetValue("name",out lvlName);
 
  string tutorial = "";
  levels[actualLevel-1].TryGetValue("tutorial",out tutorial);
 
  levels[actualLevel-1].TryGetValue("Cube",out Cube_Character);
  levels[actualLevel-1].TryGetValue("Cylinder",out Cylinder_Character);
  levels[actualLevel-1].TryGetValue("Capsule",out Capsule_Character);
  levels[actualLevel-1].TryGetValue("Sphere",out Sphere_Character);
 
  string finaltext = "";
  levels[actualLevel-1].TryGetValue("finaltext",out finaltext);

So that's it. Here you can download the fully functioning project. There are many possibilities, this is only one way, I hope you enjoyed it, give your comments!
