A.3. Tools for Processing XML

While RSS can be parsed directly using text-processing tools, XML parsers are often more convenient. Many parsers exist for using XML with many different programming languages. Most are freely available, and the majority are open source.

A.3.1. Selecting a Parser

An XML parser typically takes the form of a library of code that you interface with your own program. The RSS program hands the XML over to the parser, and the parser hands back information about the contents of the XML document. Typically, parsers do this either via events or via a document object model.
