This Way Out - Perl

And that's about it for the moment. In this article, I gave you a quick tour of WDDX, an innovative, XML-based technology designed to simplify data exchange over the Web. I showed you how you could use Perl, with its supplementary WDDX component, to serialize and deserialize a variety of different data structures, including scalars, arrays and hashes. Finally, I wrapped thngs up with a real-life demonstration of the power of WDDX, building a client-server application to transmit and retrieve WDDX-encoded information...using two different programming languages.

Needless to say, you've had a busy afternoon. Take some time off, get yourself a cup of coffee, and when you get back, drop by the following links, which have more information on WDDX.

Until next time...stay healthy!
