This tutorial covered the basics of the xml.sax package and its sub packages. This is not the only way to parse XML using Python. Hopefully in future articles we can take a look at other ways to do so and also take into account matters like XML validation and namespaces.
For the moment I would like to mention here PyXML, a toolkit with more than 200 XML-related modules and advanced implementations, including the xml.sax packages and sub packages. You can download it from here.
