How do I read XML on iOS?

I have a xml in ProjectFolder/Assets/ but I can’t load it on iOS.
Output windows print that file can’t be found.
I have tried different scripts to get file path but neither work, for example:

public static string GetiPhoneDocumentsPath () 
                string path = Application.dataPath.Substring (0, Application.dataPath.Length - 5); 
                path = path.Substring(0, path.LastIndexOf('/'));  
                return path + "/Documents"; 

string fileNameBase = Application.dataPath.Substring(0, Application.dataPath.LastIndexOf('/'));
fileName = fileNameBase.Substring(0, fileNameBase.LastIndexOf('/')) + "/Documents/" + FILE_NAME;


string fileName = Application.persistentDataPath + "/" + FILE_NAME;


Path.Combine( Application.persistentDataPath, FILE_NAME);

So… what am I doing wrong? Do I have to change some settings in Unity Editor? Where do I have to put the xml file? How do I load a xml file on iPhone/iPad?

I would recommend this address review.

I think whatever you’re trying to load might have to be in the a folder named “Resources” in the Project folder and accessed with a call to Resources.Load()
