{string path =
System.IO.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments),"Empp.xml");
XmlDocument doc = new XmlDocument();
doc.Load(path);
XmlNode root = doc.DocumentElement;
StringBuilder sb = new StringBuilder();
XmlNodeList nodeList = root.SelectNodes("Employee");
foreach(XmlNode node in nodeList){
sb.Append("Eno:");
sb.Append(node.SelectSingleNode("Eno").InnerText);
sb.Append("Ename:");
sb.Append(node.SelectSingleNode("Ename").InnerText);
sb.Append("Eadd:");
sb.Append(node.SelectSingleNode("Eadd").InnerText);
sb.Append("");
text.Text = sb.ToString();
}
// throw new NotImplementedException();
}
private void savexml(string p, string p_2, string p_3)
{
if (eteno.Text != "" && etename.Text != "" && eteadd.Text != "")
{
//throw new NotImplementedException();
string path =
System.IO.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments),
"Empp.xml");
try
{
XmlTextWriter xWriter = new XmlTextWriter(path, null);
xWriter.WriteStartDocument();
xWriter.WriteStartElement("EmployeeDetails");
xWriter.WriteStartElement("Employee");
xWriter.WriteElementString("Eno", p);
xWriter.WriteElementString("Ename", p_2);
xWriter.WriteElementString("Eadd", p_3);
xWriter.WriteEndElement();
