Save and load arrays into an XML file

Hi,

I'm trying to save and load my IOS game data. I have multiples arrays of strings, int, bools or floats. I would like to save that into an XML file, how can I do to export and import theses arrays easily? Is there a way of saving each arrays as a long string composed by the array components separated by | or ;.

So basicaly, to save I would build up a string from an array then exporting it to the xml. And to load, I would import the string the separate and fill out my array.

I've found the playerprefs (C# part) on the Unify I'm thinking to use that as a starting point.

 #region Int Array
 
     /// <summary>
     /// Stores a Int Array or Multiple Parameters into a Key
     /// </summary>
     public static bool SetIntArray(string key, params int[] intArray)
     {
         if (intArray.Length == 0) return false;
 
         System.Text.StringBuilder sb = new System.Text.StringBuilder();
         for (int i = 0; i < intArray.Length - 1; i++)
             sb.Append(intArray[i]).Append("|");
         sb.Append(intArray[intArray.Length - 1]);
 
         try { PlayerPrefs.SetString(key, sb.ToString()); }
         catch (Exception e) { return false; }
         return true;
     }
 
     /// <summary>
     /// Returns a Int Array from a Key
     /// </summary>
     public static int[] GetIntArray(string key)
     {
         if (PlayerPrefs.HasKey(key))
         {
             string[] stringArray = PlayerPrefs.GetString(key).Split("|"[0]);
             int[] intArray = new int[stringArray.Length];
             for (int i = 0; i < stringArray.Length; i++)
                 intArray[i] = Convert.ToInt32(stringArray[i]);
             return intArray;
         }
         return new int[0];
     }

Any ideas, advices?
