Subject: [ADVANCED-DOTNET] XML Validation by XSD


Hi,

                Iam a Java/C# developer, want to ask you about the
following:

                I create a sample to Validate XML file by XML Schema
(XSD file), Here is a snapshot from my code so as to let you know about
my
problem:

            class Class1
          {
  static XmlTextReader r = null;
  static XmlValidatingReader v = null;
  private static bool isValid = true;      // If a validation
error occurs,
  public static void Main(string[] args)
  {
   r = new XmlTextReader(@"Product.xml");

              v = new XmlValidatingReader(r);
   v.ValidationType = ValidationType.Schema; // XSD
validation
   v.ValidationEventHandler += new
ValidationEventHandler(MyValidationEventHandler);

   while (v.Read())
   {
   }

   v.Close();

   // Check whether the document is valid or invalid.
   if (isValid)
   {
    Console.WriteLine("\n\nDocument is valid");
   }
   else
   {
    Console.WriteLine("\n\nDocument is
invalid");
   }
   Console.ReadLine();
  }
        public static void MyValidationEventHandler(object sender,
   ValidationEventArgs args)
  {
   isValid = false;
   Console.WriteLine("Validation event\n" +
args.Message);
  }
          }

Taking the above into consideration, when I enter a valid XML file with
Valid XSD file, the output will be

"Document is valid".

So every thing is good,
but when enter an InValid XML (i.e. the XML data has more than one error
in its data types according to XSD file), only the first error will be
reported by XML validator, so what is the right way to let the XML
validator to go through all the errors in XML and reporting them all.
Thanks.
