        {
            OpenFileDialog op = new OpenFileDialog();
            op.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*";
            if (op.ShowDialog() == DialogResult.OK)
            {
                string xmlFilename = op.FileName;
                //XmlTextReader reader = new XmlTextReader(xmlFilename);
                XmlDocument xDoc = new XmlDocument();
                xDoc.Load(xmlFilename);
                XmlNodeList title = xDoc.GetElementsByTagName("title");
                MessageBox.Show("Title" + title[0].InnerText);
                XmlNodeList item = xDoc.GetElementsByTagName("item");
                for (int i = 0; i < item.Count; i++)
                {
                    //MessageBox.Show("Item" + item[i].InnerText);

                }
                XmlNodeList fl = xDoc.GetElementsByTagName("file");
                
               
                foreach (XmlNode attr in fl)
                {
                    XmlAttributeCollection att = attr.Attributes;
