Summary

This hour gave you a quick overview of the basics of XML and how it can be used to describe the structure of data. A program that will read XML files with a certain structure and display the data in a browser was also presented. This program uses JavaScript and has very few lines of actual code. It is possible to apply several sets of rules to the data in an XML file so that it is subject to many of the same restrictions that are applied to data in a database. The end result is that XML data files behave very much like data in complicated databases.
