» XML Serialization in Dot Net

We can do XML serialization using the LiquidXML classes. (another xml serializer: http://www.codeplex.com/Xsd2Code)

Actually, LiquidXML.XmlObject base from which everythign is derived has the iXMLserializable interface implemented.

For each returned object, the developers need to implement a proxy class that implements the iXmlSerialier Basically,

ReadXml(XmlReader)
WriteXml (XmlWriter)
GetSchema() but this returns nothing.
Use theXmlSchemaProvider attribute

Start of Class ¶


[XmlSchemaProvider("MySchema")]
public class SongStream : IXmlSerializable
{

GenSchema ¶


Public Function GetSchema() As _
    System.Xml.Schema.XmlSchema _
    Implements IXmlSerializable.GetSchema
    Throw New System.NotImplementedException()
  End Function

XXmlSchemaProvider ¶

      
public static XmlQualifiedName MySchema(XmlSchemaSet xs)
    {
     // This method is called by the framework to get the schema for this type.
     // We return an existing schema from disk.

     XmlSerializer schemaSerializer = new XmlSerializer(typeof(XmlSchema));
     string xsdPath = null;
     // NOTE: replace the string with your own path.
     xsdPath = System.Web.HttpContext.Current.Server.MapPath("SongStream.xsd");
     XmlSchema s = (XmlSchema)schemaSerializer.Deserialize(
         new XmlTextReader(xsdPath), null);
     xs.XmlResolver = new XmlUrlResolver();
     xs.Add(s);

     return new XmlQualifiedName("songStream", ns);
    }


[XmlSchemaProvider("MethodToGetSchema")]

WriteXML ¶


Public Sub WriteXml(ByVal writer As XmlWriter) _
      Implements IXmlSerializable.WriteXml     
      writer.WriteStartElement _
         ("employee", "urn:devx-com")       
      writer.WriteAttributeString _
         ("firstName", _firstName)        
      writer.WriteAttributeString _
         ("lastName", _lastName)     
      writer.WriteAttributeString _
         ("address", _address)
      writer.WriteEndElement()
  End Sub

ReadXML ¶

   
 void IXmlSerializable.ReadXml(System.Xml.XmlReader reader)
    {
     throw new System.NotImplementedException();

    }
