Course at a Glance
Common Business Problems
XML in the .NET Framework
After completing this module students will be able to
Explain how XML provides solutions to common business problems.
Discuss how Microsofts implementation of W3C standards for XML provides a framework for XML solutions to business problems.
Diagram XML support in the .NET Framework.
Module 2 Parsing XML
This module introduces the use of XML in the .NET Framework to help you solve common business problems. XML is a standardsdriven technology that is ideal for applications that use the Internet. Microsofts implementation of World Wide Web Consortium W3C standards ensures that applications you develop with XML in .NET will successfully communicate with other W3Ccompatible applications

This module discusses how to parse XML data from a file string or stream by using the XmlReader class. It also covers how to use the XmlTextReader to process XML as text
and how to use the XmlNodeReader to filter data by using an XPath expression and the object.

Module 3 Validating XML
This module gives an overview of XML Schema Definition XSD data types and then covers how to use the Microsoft .NET Framework XML classes to perform XML schema validation. The lesson Advanced Validation teaches how to resolve external entities how to validate XML fragments and how to validate XML by using a Document Type Definition DTD.

Resolve a Uniform Resource Identifier URI reference to a schema or DTD.
Create an application that uses the .NET Framework XML classes and an XSD schema or a DTD to validate wellformed XML.
Module 4 Writing XML
Writing XML is a central skill in developing XMLbased applications. This module describes the .NET Framework classes that are used to write XML with or without namespaces. The module also explains how to control the format and validity of XML as it is being written.

Control indentation and other code format characteristics when generating XML.
Write XML that preserves characters that are normally represented by using escape characters.
Module 5 Querying XML
This module explains the process of querying an XML document by using XPath. It explains how to write code to load an XML document and how to create a navigation cursor by using an XPathNavigator object. It also explains how to create your query by using an XPathDocument object and how to examine the result types. In addition this module describes how to compile your query and evaluate your results.
