Question

Answer 1

I have created my custom class for binding XML to DROPDOWN. code of custom class is following

public class XmlReaderBinder
    {
        public static void BindDropDown(ComboBox dd, string elementName, string nodeNameValue,
                          string nodeNameText, string xmlPath)
        {
            HttpContext context = HttpContext.Current;
            XmlTextReader reader = null;
            ArrayList lstItems = new ArrayList();
            string val = String.Empty;
            string txt = String.Empty;
            bool inTarget = false;
            try
            {
                reader = new XmlTextReader(xmlPath);
                //Allow for object to object comparison rather than string comparison
                object target = reader.NameTable.Add(elementName);
                object targetVal = reader.NameTable.Add(nodeNameValue);
                object targetTxt = reader.NameTable.Add(nodeNameText);
                //Read through the XML stream and find proper tokens
                while (reader.Read())
                {
                    if (reader.NodeType == XmlNodeType.Element)
                    {
                        //Check attribute names
                        if (reader.Name.Equals(target))
                        {
                            inTarget = true;
                            //Get attribute values (if any)
                            if (reader.HasAttributes)
                            {
                                if (reader.MoveToAttribute(nodeNameValue))
                                {
                                    val = reader.Value;
                                    reader.MoveToElement();
                                }
                                if (reader.MoveToAttribute(nodeNameText))
                                {
                                    txt = reader.Value;
                                    reader.MoveToElement();
                                }
                            }
                            if (val == "" || txt == "") val = txt = String.Empty;
                            if (val != String.Empty && txt != String.Empty)
                            {
                                ListItem item = new ListItem(txt, val);
                                lstItems.Add(item);
                                //Attribute values override any child nodes values
                                //so if we match on attributes then don't look at any 
                                //child nodes
                                inTarget = false;
                                val = txt = String.Empty;
                            }
                        }
                        else if (inTarget)
                        {  //Check for child nodes that match
                            if (reader.Name.Equals(targetVal))
                            {
                                val = reader.ReadString();
                                if (val == "") val = String.Empty;
                            }
                            if (reader.Name.Equals(targetTxt))
                            {
                                txt = reader.ReadString();
                                if (txt == "") txt = String.Empty;
                            }
                            if (val != String.Empty && txt != String.Empty)
                            {
                                ListItem item = new ListItem(txt, val);
                                lstItems.Add(item);
                                val = txt = String.Empty;
                            }
                        }
                    }
                    if (reader.NodeType == XmlNodeType.EndElement || reader.IsEmptyElement)
                    {
                        if (reader.Name.Equals(target))
                        {
                            inTarget = false;
                        }
                    }

                }
                if (lstItems.Count > 0)
                {
                    foreach (ListItem item in lstItems)
                    {
                        dd.Items.Add(item);
                    }

                }
                else
                {
                    ListItem item = new ListItem("No Data Available", "");
                    dd.Items.Add(item);
                }
                lstItems.Clear();
            }
            catch (Exception exp)
            {
                context.Response.Write(exp.Message);
            }
            finally
            {
                if (reader != null) reader.Close();
            }
        }

    }

And after creating class you can call class function 'BindDropDown' like below mentioned ways.

XmlReaderBinder.BindDropDown('DROP DOWN NAME', "publicationsList", "publication", "Name", xmlPath);

Hope it will help for you.
