441.  XML Parsing Using C# and .NET

Rev. 2.1

 

This two-day course teaches the different types of XML parsing available in .NET.  It covers the different parsing methodologies available from Microsoft. and gives an overview of XML technologies in the .NET Framework. Both the streaming model of XmlReader and XmlWriter and the Document Object Model (DOM) are covered in detail. Validation using DTD and XmlSchema is discussed. New features in System.Xml in .NET 2.0 are discussed in the context of where the topics are covered. Visual Studio 2005 is used as the development environment.

 

The course includes extensive programming examples, including a progressively developed case study. Upon completion of this course the student will be equipped to program XML applications in .NET and understand which parsing method to apply for the problem domain.
