The "area code" for XML namespaces is a URI, which is associated with a prefix for the namespace.We define a namespace using an xmlns declaration, followed by the prefix, which is equal to a URI that uniquely identifies the namespace: Parsers can now recognise both meanings of "film type" and handle them accordingly.One of the most exciting recent advances in computing has been XML. Before we look into the specifics of XML, it is important to know why XML exists and where it can be used.Designed as a stricter and simpler document format than SGML, XML is now used everywhere to produce cross-platform interoperable file formats. A proper understanding will allow you to use it effectively in your projects.The full XML specification can be read here, although, as we'll see shortly, .NET gives you the tools to write valid XML automatically.There might be thousands of telephone numbers of 545-321.

It doesn’t say how to display the data or what to do with data, just as a text file doesn’t.

Sometimes, it doesn't make sense for information to appear between opening and closing tags.

We can see clearly that there is a catalogue containing CDs, each of which contains some tracks (music aficionados will notice that I have cut down the track listings for space! You can also see that XML can be less efficient than some other file formats.

Yet, in many cases, the loss in efficiency that results from the increased size can be made up by the speed of processing a well-defined XML file, as parsers (programs that read XML) can predict the structure.
