XML Programming Using C# and .NET

This comprehensive and practical four-day course builds skills in .NET's XML processing APIs - chiefly parsing using XmlReader and the Document Object Model (DOM), writing XML streams using XmlWriter, transformations using XPath and XSLT, and the new LINQ to XML, all using the .NET Framework XML classes and the C# language. It also covers XML serialization according to XML Schema and the tight coupling between XML and ADO.NET. The course is intended for students with a working knowledge of XML who want to build XML applications or components using .NET and the C# language. Everything in the course adheres to W3C and .NET standards for highly portable code. Visual Studio 2014 with .NET 4.5.1 is used as the development environment.

The course includes extensive programming examples, a progressively developed case study, and several tools for manipulating XML documents. All source code is in C# and is provided with the course. A separate Lab Manual provides detailed instructions for laboratory exercises with console and Windows Forms client programs. A parallel course, 4126, XML for Web Applications Using C#, has lab exercises with console and Web Forms client programs. The Student Guide and Lab Manual are bound together in a single volume.

Upon completion of this course the student will be equipped to program XML applications in .NET and understand which XML and .NET technologies to apply for the problem domain.

• Ability to read and to write well-formed XML. A working knowledge of programming the .NET Framework using C#. A working knowledge of ADO.NET is recommended for the portion of the course dealing with ADO.NET and XML.

On completion of this course, the student should be able to

• Understand the purpose of the .NET Framework XML classes
• Parse XML data streams using XmlReader classes
• Validate XML data streams that are described by a DTD or an XML Schema
• Use the XmlWriter class to create XML data streams
• Modify, create and delete information in an XML document using the Document Object Model (DOM) .NET classes.
• Use XML Serialization to persist XML data
• Acquire a working knowledge of the use of ADO.NET with XML
• Use XPath to query for content in an XML document
• Use the XPathNavigator class to parse and edit XML documents
• Use XSLT to transform XML documents into text, HTML or other XML
• Use Language Integrated Query (LINQ) to manipulate XML documents
