System_CAPS_noteNote

The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.

The following example displays each node including its depth, line number, and line position.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{

   // Create the XML fragment to be parsed.
   String^ xmlFrag = "<book>\n"
   "<misc>\n"
   "<style>paperback</style>\n"
   "<pages>240</pages>\n"
   "</misc>\n"
   "</book>\n";

   // Create the XmlNamespaceManager.
   XmlNamespaceManager^ nsmgr = gcnew XmlNamespaceManager( gcnew NameTable );

   // Create the XmlParserContext.
   XmlParserContext^ context = gcnew XmlParserContext( nullptr,nsmgr,nullptr,XmlSpace::None );

   // Create the reader.
   XmlValidatingReader^ reader = gcnew XmlValidatingReader( xmlFrag,XmlNodeType::Element,context );
   IXmlLineInfo^ lineInfo = (dynamic_cast<IXmlLineInfo^>(reader));
   if ( lineInfo->HasLineInfo() )
   {

      // Parse the XML and display each node.
      while ( reader->Read() )
      {
         switch ( reader->NodeType )
         {
            case XmlNodeType::Element:
               Console::Write( " {0} {1}, {2}  ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition );
               Console::WriteLine( "< {0}>", reader->Name );
               break;

            case XmlNodeType::Text:
               Console::Write( " {0} {1}, {2}  ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition );
               Console::WriteLine( " {0}", reader->Value );
               break;

            case XmlNodeType::EndElement:
               Console::Write( " {0} {1}, {2}  ", reader->Depth, lineInfo->LineNumber, lineInfo->LinePosition );
               Console::WriteLine( "</ {0}>", reader->Name );
               break;
         }
      }
   }


   // Close the reader.
   reader->Close();
}
