XML Building XML-Based Web Applications Part 4

This is the fourth course in a five part series dedicated to coverage of the Document Object Model. This course will provide the learner with a solid understanding of its importance and practice of its usage. The structure of the DOM is presented in detail, along with information on accessing DOM documents and navigating DOM trees and retrieving content. Dynamic transformation on the server and clinet is covered. The manipulation and display of XML data is covered. The final area of DOM to be covered is the posting of XML data. The creation of an XML packet, its sending and processing are covered.

• Identify features of the XML parser.
• Identify features of the Document Object Model (DOM) tree structure.
• Identify features of the Node object.
• Identify ways of searching for element nodes in the DOM tree.
• Identify syntax for accessing the content of an element in the DOM tree.
• Sequence the steps for creating a new element in a DOM tree.
• Sequence the steps to relay information between a client and a Web server by using XML.
• Sequence the steps involved in building an XML data packet on a client and posting it to the server.
• Identify features of building an XML data packet.

The intended audience for this course include individuals who operate a software development environment using Microsoft Windows DNA technologies and building Web applications. Job profiles include: Technical Manager, Application Developer, System Analyst, and Software Engineer. Suggest a working knowledge of COM+, IIS, ASP, and Visual Basic, and preferably have used Visual InterDev. In addition, learners should have taken the first three parts of this series (73221-73223).
