    // Define input parameters
    var inputData = {
        SourceFile:"c:\\Data\\Others\\landmarks.lmx", 
        MimeType:"application/vnd.nokia.landmarkcollection+xml"
        };
    var inParams = {Type:"Landmark", Data:inputData};
 
    // Define result value
    var outParams = landmark.Import(inParams);
    var outList = outParams.ReturnValue;
    var i = 0;
    if (outParams.ErrorCode == 0) {
        var outputEntry = null;
        do {
            i++;
            outputEntry = outList.next();
            if (null != outputEntry) {
                text_txt.text += "Landmark "+i+"\r"+outputEntry.LandmarkName+
                    "\r"+outputEntry.id+"\r";
            } else {
                break;
            }
        } while (true);
    } else {
        var errorId = outParams.ErrorCode;
