Hi devarajan.v

Yes, .Net Supports validating XML document against DTDS.

In .Net framework System.Xml Namespace contains all the neccessary classes and methods to do this.


Some of the Classes for this perpose are...

XmlTextReader in System.Xml Namespace

XmlValidatingReader in System.Xml Namespace

XmlSchema in System.Xml.Schema Namespace

XmlSchemaCollection in System.Xml.Schema Namespace


Hope usefull to u..

Oxygen

private void ValidatingProcess(string XSDPath, string XMLPath)
{
try
{

Reader = new XmlTextReader(XMLPath);


StreamReader SR = new StreamReader(XSDPath);


XmlSchema Schema = new XmlSchema();



Schema = XmlSchema.Read(SR,
new ValidationEventHandler(ValidatingReader_Validation EventHandler));


XmlValidatingReader ValidatingReader = new XmlValidatingReader(Reader);

ValidatingReader.ValidationType = ValidationType.Schema;

ValidatingReader.Schemas.Add(Schema);



ValidatingReader.ValidationEventHandler +=
new ValidationEventHandler(ValidatingReader_Validation EventHandler);


while (ValidatingReader.Read())
{/*Empty loop*/}

}

catch (UnauthorizedAccessException AccessEx)
{
throw AccessEx;
}
catch (Exception Ex)
{
throw Ex;
}
}

private void ValidatingReader_ValidationEventHandler(object sender,
ValidationEventArgs args)
{
// 10- Implement your logic for each validation iteration
string strTemp;
strTemp = "Line: " + this.Reader.LineNumber + " - Position: " +
this.Reader.LinePosition + " - " + args.Message;

this.Results.Add(strTemp);
}
