How Do I...Validate XML using the XmlSchemaValidator Class?

This sample illustrates how to validate XML data by using the XmlSchemaValidator class. The XmlSchemaValidator class is useful in advanced scenarios. It lets you validate an XML infoset in-place without having to serialize it as an XML document, and then reparse the document by using a validating XML reader. The sample deserializes XML data by using the XmlSerializer class, and then passes the XML data to the methods of the XmlSchemaValidator class.

XmlSerializer serializer = new XmlSerializer(typeof(books)); Books myBooks = (books)serializer.Deserialize(reader); ... XmlSchemaValidator xsv = CreateValidator(); xsv.Initialize(); xsv.ValidateElement("books", "http://www.example.com/my-bookshelf", schemaInfo); ... Dim serializer As New XmlSerializer(GetType(books)) Dim myBooks As Books = CType(serializer.Deserialize(reader), Books) ... Dim xsv As XmlSchemaValidator = CreateValidator() xsv.Initialize() xsv.ValidateElement("books", "http://www.example.com/my-bookshelf", schemaInfo) ...
