Object reference not set to an instace of an object (JS)

I'm going crazy, where is the problem?

 public class Lang
 {
     private var Strings : Hashtable;
 
     function Lang (path : String, language : String) {
         var data : TextAsset = Resources.Load(path);
         var xml : XmlDocument = new XmlDocument();
         xml.Load(data.text);
 
 ...

The error is on the last line.

Call code:

 function OnEnable () {
     LMan = new Lang("lang", Application.systemLanguage.ToString());
 }

The file is on root directory.

If I change the Constructs to:

 function Lang (path : String, language : String) {
     var xml : XmlDocument = new XmlDocument();
     xml.Load(path);

And the call code to:

 LMan = new Lang("lang.xml", Application.systemLanguage.ToString());

Works! but not in Android!

Sorry for my bad english.

• Edit -- Ok, now work! I change:

  function Lang (path : String, language : String) { var data : TextAsset = Resources.Load.(path); var xml : XmlDocument = new XmlDocument(); xml.LoadXml(data.text);

and i add the XML file to the directory Resources.

 function Lang (path : String, language : String) {
     var xml : XmlDocument = new XmlDocument();
     xml.Load(path);

 L$$anonymous$$an = new Lang("lang.xml", Application.systemLanguage.ToString());
