Writing SAX Drivers for Non-XML Data:
“In a previous column, we covered the basics of the Simple API for XML (SAX) and the modules that implement that interface in Perl. Over the course of the next two months we will move beyond these basic topics to look at two slightly more advanced ones: creating drivers that generate SAX events from non-XML sources and writing custom SAX filters. If you are not familiar with the way SAX works, please read High-Performance XML Parsing With SAX before proceeding.”
