I'll also walk you through some of the different scenarios and ways in which you can validate an XML document with an XSD schema programmatically (see Table 1). NET Framework 2.0 means you can perform XML data validation against a Document Type Definition (DTD) or an XML schema. XSD schema-based validation is the industry-accepted standard and will be the method of XML validation in this article.

You specify the validation settings as well as a Validation Event Handler method using the Xml Reader Settings object. I won't explain how to validate XML data using DTDs because those are not typically used outside legacy applications.

Create (new Xml Text Reader(file), settings); Check the MSDN documentation for Xml Validating Reader and you'll see in the [Obsolete Attribute] attribute this: "Use Xml Reader created by Xml Reader.

Validation Event Handler = delegate( object sender, Validation Event Args e ) ; Xml Reader reader = Xml Reader.

NET Framework is the foundation of Microsoft's next generation of development tools. NET and then details the XML tools that are provided by the Framework and the Visual Studio . Code samples in this chapter are written in the C# language. NET initiative has its origins in the increasing importance of the Web in almost all areas of application development.

Given the increasing importance of XML in all areas of programming and data processing, the inclusion of powerful, integrated XML support in . This is a new language introduced with Visual Studio . Previous development tools, exemplified by Visual Studio version 6.0, were designed for the needs of a decade ago, when the ruling paradigm was applications that were stand-alone or were distributed over a local area network (LAN). NET Framework provides a comprehensive set of classes that are designed for just about any programming task you can imagine.

Then it creates an instance of the mainwindow class, shows it, and starts the Qt event loop: slot the content of the instance selection is adapted to the selected schema and the corresponding schema is loaded from the resource file and displayed in the schema viewer.

Xml namespace is probably the most significant of these namespaces if only because it includes classes such as Xml Document, Xml Node Reader, Xml Reader, and Xml Reader Settings, which are critical in validating XML data.

As you can modify the content of the instance editor, different instances can be tested and validation error messages analysed.

The example's main() function creates the standard instance of QApplication.

The user can select the valid or invalid instance document, change it and validate it again.

The UI for this example was created using Qt Designer: The UI consists of three parts, at the top the XML schema selection and the schema viewer, below the XML instance selection and the instance editor and at the bottom the validation status label next to the validation button.

You then perform the validation during the reading and parsing operations of the factory-created Xml Reader object. Validation is the process of enforcing rules on the XML content either through an XSD schema or a DTD or XDR schema.
