Csharp/CSharp Tutorial/XML/Xml Atrributes

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();

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(); 
     }    
   }
 }
