Course Outline

Module 1: Introduction to XML in the .NET Framework

This module introduces the use of XML in the .NET Framework to help you solve common business problems. XML is a standards-driven technology that is ideal for applications that use the Internet. Microsoft's implementation of World Wide Web Consortium (W3C) standards ensures that applications you develop with XML in .NET will successfully communicate with other W3C-compatible applications

Lessons

• Overview
• Course at a Glance
• Common Business Problems
• XML in the .NET Framework

• Explain how XML provides solutions to common business problems.
• Discuss how Microsoft's 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 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.

Lessons

• Overview of XML Parsing
• Parsing XML Using XmlTextReader
• Creating a Custom Reader

Lab 2.1: Parsing XML

• Exercise 1: Building an XML Web Service to Parse XML

• Create a Stream object from an XML file.
• Build a mutable string by using the StringBuilder object.
• Handle errors in the form of XML.
• Parse XML as text by using the XmlTextReader object.
• Create a custom XmlReader 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).

Lessons

• Examining Schemas
• Validating XML While Parsing
• Advanced Validation

Lab 3.1: Validating XML

• Exercise 1: Extend an XML Web Service to Validate XML

• Instantiate an XML validating reader.
• Associate one or more XML schemas with an XML validating reader.
• Handle errors that result when a validating reader processes invalid XML.
• Create an application that uses the .NET Framework XML classes and XML schemas to validate an XML fragment.
• 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 well-formed XML.

Module 4: Writing XML

Writing XML is a central skill in developing XML-based 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.

Lessons

• Overview of Generating XML Documents
• Writing XML
• Generating XML with Namespaces
• Controlling XML Format and Converting XML

Lab 4.1: Writing XML

• Exercise 1: Building an XML Web Service to Write XML

• Use the XmlTextWriter class to write well-formed XML.
• Generate namespaces for elements and attributes.
• 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.

Lessons

• Introduction to Querying XML Using XPath
• Creating and Navigating a Document Cache
• Executing Your Query

Lab 5.1: Querying XML Documents Using XPath

• Exercise 1: Creating and Loading an XML Data Cache
• Exercise 2: Compiling and Executing Queries That Return Nodes
• Exercise 3: Compiling and Executing Queries That Return Numbers
• Exercise 4: Compiling and Executing Queries That Return Strings

• Describe the business reasons for querying XML documents by using XPath.
• Cache XML data for querying by using an XPathDocument object.
• Create an XPathNavigator object to navigate through an XML document.
• Compile and evaluate the result of an XPathExpression object.
• Iterate through an XmlNodeList object returned by an XPath expression.

Module 6: Manipulating Cached XML

This module introduces the XML Document Object Model (XML DOM) and explains how to locate and manipulate XML by using the DOM.

Lessons

• Introduction to the XML Document Object Model
• Navigating XML Using the DOM
• Creating New Nodes
• Modifying and Deleting Nodes

Lab 6.1: Manipulating Cached XMLDocument Objects

• Exercise 1: Loading an XML Document
• Exercise 2: Navigating an XML Document

• Open and save XML by using the DOM.
• Locate XML by using the DOM.
• Create nodes in the XML node tree.
• Modify and delete nodes in the XML node tree.

Module 7: Transforming XML

This module explains the process of transforming XML documents. The module teaches the student how to apply an XSLT transformation to an XML document by using the .NET XML classes. It does not teach XSLT syntax or commands.

Lessons

• Introduction to Transforming XML
• Programmng the XslTransform Class
• Extending XSLT Style Sheets

Lab 7.1: Transforming XML Documents

• Display XML by using the ASP.NET Xml Web Forms control.
• Pass parameters to XSLT style sheets.
• Apply a style sheet that references an extension object.

Module 8: Serializing Objects as XML

This module provides students with the skills needed to create XML documents from the data contained within programmatic objects. This process is referred to as serialization and can be used to persist object data or to share object data between applications.

Lessons
