Understanding XML Namespaces - Introduction

shohoudy

Introduction

Understanding XML namespaces is essential to understanding and building Web services. Unfortunately, most developers do not understand how XML namespaces work and get confused when they see all the colons and URLs. The funny thing is, namespaces are so simple that once you understand them you wonder why you had trouble understanding them in the first place. I wrote this article to help you get over the initial hump of understanding XML namespaces, and to show you how they are used in XML documents.

This article is geared towards Visual Basic developers. If your work involves HTML more than programming, there’s an excellent namespace tutorial that speaks to your needs.

Yasser started programming at the age of 12 when he wrote his first text-based game on a Commodore PET. He's since moved to IBM mainframes then to Microsoft technologies and has worked as Systems Engineer for IBM and a Chief Architect for Best Software (now Sage Software). Now an independent consultant and trainer, Yasser specializes in XML and Web services and has authored a book on Web Services for Addison Wesley. A Microsoft Most Valuable Professional (MVP) for ASP.NET, Yasser speaks at industry conferences including VS Live and VS Connections and his articles appear regularly in VSM, XML Magazine, and MSDN Magazine. Yasser also publishes the monthly .NET Web Services newsletter.
