Esempio

Nell'esempio seguente viene convalidato un documento XML utilizzando .XmlSchemaCollection

#using <System.Xml.dll>
#using <System.dll>

using namespace System;
using namespace System::Xml;
using namespace System::Xml::Schema;
using namespace System::IO;
public ref class ValidXSD

   static void main()
   {
      XmlSchemaCollection^ sc = gcnew XmlSchemaCollection;
      sc->ValidationEventHandler += gcnew ValidationEventHandler( ValidationCallBack );
      sc->Add( nullptr, "books.xsd" );
      if ( sc->Count > 0 )
      {
         XmlTextReader^ tr = gcnew XmlTextReader( "notValidXSD.xml" );
         XmlValidatingReader^ rdr = gcnew XmlValidatingReader( tr );

Commenti

Gli schemi vengono caricati usando il Add metodo , al momento in cui lo schema è associato a un URI (Uniform Resource Identifier) dello spazio dei nomi. Per gli XML Schema, in genere si tratta della targetNamespace proprietà dello schema.

Anche se questa classe archivia sia xml Schema che schemi XDR, qualsiasi metodo e proprietà che accetta o restituisce un oggetto XmlSchema si applica solo a XML Schema.

Questa versione del prodotto supporta la raccomandazione W3C (World Wide Web Consortium) XML Schema disponibile in XML Schema Part 1: Structures and XML Schema Part 2: Datatypes ( Xml Schema Part 2: Datatypes). Un XML Schema deve fare riferimento allo spazio dei nomi http://www.w3.org/2001/XMLSchema W3C Schema nel relativo elemento dello schema. Per un esempio, vedere il Add metodo .

XmlSchemaCollection può essere usato da XmlValidatingReader per una convalida efficiente dei dati.
