==If it is an Attribute==

<source lang="csharp">using System;
using System.Xml;
using System.Collections.Generic;
using System.Text;
class Program{
static void Main(string[] args)
{
XmlDocument itemDoc = new XmlDocument();
itemDoc.Load("items.xml");
Console.WriteLine("DocumentElement has {0} children.",itemDoc.DocumentElement.ChildNodes.Count);
foreach (XmlNode itemNode in itemDoc.DocumentElement.ChildNodes)
{
XmlElement itemElement = (XmlElement)itemNode;
Console.WriteLine("\n[Item]: {0}\n{1}", itemElement.Attributes["name"].Value,itemElement.Attributes["description"].Value);
if (itemNode.ChildNodes.Count == 0)
Console.WriteLine("(No additional Information)\n");
else
{
foreach (XmlNode childNode in itemNode.ChildNodes)
{
if (childNode.Name.ToUpper() == "ATTRIBUTE")
{
Console.WriteLine("{0} : {1}",
childNode.Attributes["name"].Value,
childNode.Attributes["value"].Value);
}
else if (childNode.Name.ToUpper() == "SPECIALS")

Console.WriteLine("*{0}:{1}",
specialNode.Attributes["name"].Value,

==Using XmlAttributeOverrides with XmlSerializer==

<source lang="csharp">using System;
using System.IO;
using System.Reflection;
using System.Xml.Serialization;
public class Customer
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string EmailAddress { get; set; }
public override string ToString()
{
return string.Format("{0} {1}\nEmail: {2}",FirstName, LastName, EmailAddress);
}
}
public class Tester
{
static void Main()
{
Customer c1 = new Customer{
FirstName = "A",
LastName = "G",
EmailAddress = "o@a.ru"
};
XmlAttributeOverrides overrides = new XmlAttributeOverrides();
Type customerType = typeof(Customer);
foreach (PropertyInfo prop in customerType.GetProperties())
{
XmlAttributes attrs = new XmlAttributes();
attrs.XmlAttribute = new XmlAttributeAttribute();
overrides.Add(customerType, prop.Name, attrs);
}
XmlSerializer serializer = new XmlSerializer(customerType, overrides);
StringWriter writer = new StringWriter();
serializer.Serialize(writer, c1);
string xml = writer.ToString();
Console.WriteLine("Customer in XML:\n{0}\n", xml);
Customer c2 = serializer.Deserialize(new StringReader(xml)) as Customer;
Console.WriteLine("Customer in Object:\n{0}", c2.ToString());
}
}</source>

==Write attribute value==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.ruponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Xml.XPath;
public class MainClass
{
public static void Main()
{
XmlDocument doc;
XPathNavigator editor;
XmlWriter writer;
doc = new System.Xml.XmlDocument();
doc.Load("pubs.xml");
editor = doc.CreateNavigator().SelectSingleNode("/pubs");
writer = editor.AppendChild();
writer.WriteStartElement("publishers");
writer.WriteAttributeString("pub_id", "1234");
writer.WriteAttributeString("pub_name", "A");
writer.WriteEndElement();
writer.Close();
doc.Save("output.xml");
}
}</source>

==XmlTextReader: move to content and move to first attribute==

<source lang="csharp">using System;
using System.Xml;
class MainClass
{
static void Main(string[] args)
{
XmlTextReader reader = new XmlTextReader(@"C:\books.xml");

reader.MoveToContent();
reader.MoveToFirstAttribute();
Console.WriteLine("First Attribute Value" +reader.Value);
Console.WriteLine("First Attribute Name" +reader.Name);
}
}</source>

==XmlTextReader: read all attributes==

<source lang="csharp">using System;
using System.Xml;
class MainClass
{
static void Main(string[] args)
{
XmlTextReader reader = new XmlTextReader(@"C:\books.xml");

while (reader.Read())
{
if (reader.HasAttributes)
{
Console.WriteLine(reader.Name + " Attribute");
for (int i = 0; i < reader.AttributeCount; i++)
{
reader.MoveToAttribute(i);
Console.WriteLine("Nam: "+reader.Name +", Value: "+ reader.Value);
}
reader.MoveToElement();
}
}
}
}</source>
