Handling XML in Perl

Handling XML in Perl - module P668

The Extensible Markup Language (XML) is an important tool in structuring data. This training module covers the two major XML engines that are supported by Perl modules, and teaches you how to program using them. We also cover handling XSLT in Perl.
