Examples

The following example validates an XML document using the 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
{
public:
   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 );
         rdr->ValidationType = ValidationType::Schema;
         rdr->Schemas->Add( sc );
         rdr->ValidationEventHandler += gcnew ValidationEventHandler( ValidationCallBack );
         while ( rdr->Read() )
                  ;

   }

   {
      Console::WriteLine( "Validation Error: {0}", e->Message );

Remarks

Schemas are loaded using the Add method, at which time the schema is associated with a namespace Uniform Resource Identifier (URI). For XML Schemas, this will typically be the targetNamespace property of the schema.

Although this class stores both XML Schemas and XDR schemas, any method and property that takes or returns an XmlSchema applies to XML Schemas only.

This version of the product supports the World Wide Web Consortium (W3C) XML Schema recommendation located at XML Schema Part 1: Structures and XML Schema Part 2: Datatypes. An XML Schema must reference the W3C Schema namespace http://www.w3.org/2001/XMLSchema in its schema element. See the Add method for an example.

XmlSchemaCollection can be used by XmlValidatingReader for efficient data validation.
