Overview

This class is an implementation of the XmlTextReader class and extends the XmlTextReader with validation features. It can be used to perform validation against XML Schemas and Document Type Definitions (DTDs).

Example (VB.NET): How to validate a document with the XmlValidatingReader.

The example below loads the contents of an XML document into a FileStream object that is subsequently assigned to the XmlValidatingReader object. We then initiate the XmlValidatingReader.Read method in an empty While/End loop to activate the validation.

Dim objXmlValidatingReader As System.Xml.XmlValidatingReader

Dim objFileStream As System.IO.FileStream

Dim strValues As String

Try

objFileStream = New System.IO.FileStream("c:\sample.xml", System.IO.FileMode.Open)

objXmlValidatingReader = New System.Xml.XmlValidatingReader(objFileStream, XmlNodeType.Element, Nothing)

While (objXmlValidatingReader.Read())

End While

strValues = "Successful validation."

Catch objXmlException As System.Xml.XmlException

strValues = objXmlException.Message

End Try
