Read .xml file content with WWW class

Hi all, I need to retrieve an .xml file inside the StreamingAssets folder using the WWW class and then read every single line inside it.

I'm able to retrieve the file and get it into a www type variable, but then I really can't read anything from it. I'd like to read it as it was a normal .xml file, but for some reasons I can't.

The error I get is: IsolatedStorageException: Could not find file "/UnityEngine.WWW".

This is the code of the retrieval:

 string gesturesPath = System.IO.Path.Combine (Application.streamingAssetsPath, "Gestures/" + fileName + "/");
  
         if (gesturesPath.Contains ("://")) {
  
             Debug.Log("gesturesPath: " + gesturesPath);
  
             for (int i = 0; i < 2; i++) {
                 WWW www = new WWW (gesturesPath + fileName + i + ".xml");
                 while (!www.isDone) {}
  
                 trainingSet.Add (GestureIO.ReadGestureFromFile (www.ToString()));
             }
  
 // some other code...

This is the code of the function to read from the .xml file:

 public static Gesture ReadGestureFromFile(string fileName) {
  
             XmlTextReader xmlReader = null;
             Gesture gesture = null;
          
             try {
              
                 xmlReader = new XmlTextReader(File.OpenText(fileName));
                 gesture = ReadGesture(xmlReader);
              
             } finally {
              
                 if (xmlReader != null)
                     xmlReader.Close();
             }
          
             return gesture;
         }

I assume that www.ToString() is not the right way to get the string path of the file the www variable is storing, and www.text is not what I need.

Oh yes, and the www variable returns "/UnityEngine.WWW", which I don't know what it is.

Any idea?

Thank you in advance and have a nice day!
