XML Parsing in a Producer-Consumer Model (O'Reilly)
XML plays a vital role in integrating business-to-business applications. To parse XML files, these applications use either a Simple API for XML (SAX) or a Document Object Model (DOM) parser. Parsing in single-threaded applications is straightforward. However, it is quite complex and challenging in a multithreaded application, such as an application server, because the applications often create a dedicated thread to parse XML, serving many concurrently running threads with the parsed data. This article describes one implementation of parsing XML in concurrent applications."
