Think there's no such thing as platform independence? Thinkagain. This article introduces you to WDDX, a platform-neutral way toexchange data structures across the Web, and shows you how you can putit to work using the Perl WDDX module.
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!
