XML::Toolkit is the results of years of study, and two large production
projects. It's a collection of tools to make some of the pain of integrating
XML into an application go away. XML::Toolkit was designed to handle large XML
document sets, to be flexible, and to produce valid clean correct XML.
This talk will cover the history of the project, the various tools in the
toolkit and example applications based on real-world code.
