    if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "pro"))
    {
        Console.WriteLine(reader["NAME"]);
    }
    else if((reader.NodeType == XmlNodeType.Element) && (reader.Name == "scode"))

        Console.WriteLine(reader["ID"]);
       //what do I put here to get the value????
    }
}
reader.Close();

What you're looking for is:

Console.WriteLine(reader.ReadInnerXml());

I personally prefer LINQ to XML. If you haven't looked into it, you should. You can achieve the same thing in a cleaner manner.

at the start of your c# file put the following:

 using System.Linq; using System.Xml.Linq; // loads the linq to xml part 

Most XML files are much bigger than just one element. So for that, your code would be something like this:

 // Load XML file as an IEnumerable. This allows you to query it. var xmlDoc = XDocument.Load(file) .Elements("pro") .Select(pro => new { Name = pro.Attribute("NAME").Value, Scode = pro.Elements("scode").Select(scode => new { ID = scode.Attribute("ID").Value, Val = scode.Value }) }); // loop through each <pro> element foreach (var pro in xmlDoc) { // Get Pro Name Console.WriteLine(pro.Name); // loop through each <scode> element inside <pro> foreach(var scode in pro.Scode) { // Get Scode ID: Console.WriteLine(scode.ID); // Get Scode Value: Console.WriteLine(scode.Val); } } 

If your XML is only a SINGLE element, you can do this:

 // Load XML file: var pro = XElement.Load("file.xml"); // Get Pro Name pro.Attribute("NAME").Value; // Get Scode ID: pro.Element("scode").Attribute("ID").Value; // Get Scode Value: pro.Element("scode").Value; 

Answer 2

Consider the following code snippet...

XDocument doc = XDocument.Load("file.xml");
foreach (XElement element in doc.Descendants("pro"))
{
    Console.WriteLine(element.Attribute("NAME").Value);
}

foreach (XElement element in doc.Descendants("scode"))
{
    Console.WriteLine(element.Value);
}

Good Luck!
