XmlException when trying to read/write XML from iOS device

I am trying to read and write XML to iOS. Everything works fine in the iOS simulation, but when I try to build an app on my device the problems seems to be starting.

I have added the xml file to Copy Bundle Resources with "Copy items into destination group´s folder (if needed) check and "Create groups for any added folders" checked.

This is my code for loading the XML file :

 string path = path = Application.persistentDataPath + "/gamexmldata.txt";
 
 public void LoadFromXml()
 {
 Debug.Log ("Du nådde LoadXML metoden");
 
 
 XmlDocument xmlDoc = new XmlDocument();
 
 if(File.Exists(path))
 {
 Debug.Log("Filen finnes");
 Debug.Log(path.ToString());
 xmlDoc.Load(path);
 
 
 XmlNodeList transformList = xmlDoc.GetElementsByTagName("rotation");
 
 foreach (XmlNode transformInfo in transformList)
 {
 XmlNodeList transformcontent = transformInfo.ChildNodes;
 
 foreach (XmlNode transformItens in transformcontent)
 {
 if(transformItens.Name == "x")
 {
 
 Debug.Log(transformItens.InnerText);
 resultatFraXML += transformItens.InnerText;
 }
 if(transformItens.Name == "y")
 {
 
 Debug.Log(transformItens.InnerText);
 resultatFraXML += transformItens.InnerText;
 }
 if(transformItens.Name == "z")
 {
 Debug.Log(transformItens.InnerText);
 
 resultatFraXML += transformItens.InnerText;
 }
 if(transformItens.Name == "name")
 {
 resultatFraXML += transformItens.InnerText;
 guitext.text = resultatFraXML;
 GameControl.control.outputXml = resultatFraXML;
 Debug.Log(resultatFraXML);
 }
 
 }
 }
 
 }
 
 }
 

The error I get is :

 XmlException: Document element did not appear. file:///var/mobile/Applications/47C26549-9CB0-46C2-9906-66399A5E515C/Documents/gamexmldata.txt Line 1, position 1.

I was thinking it might be UTF-8 and BOM problems, but I have done all converting and checking etc. Can´t find any BOM at all.

By accident the same error came when I played around with the Unity editor and then it appeared that the file was empty. Earlier on my debugging I did a File.Create in the code. Could it be that I have a empty file in the app that has NO data in it all? Or is the file placed in a wrong directory?

Any good ideas to why I get this kind of error?
