Apache Cocoon ^[1] and Forrest ^[2] are exciting applications of XML and XSLT in an internet environment. Apache Cocoon is a framework which binds URIs to SAX ^[3]-driven content-generating XML pipelines, while Forrest is a blueprint Cocoon application specifically aimed at software project documentation, making extensive use of XSLT for the creation of skinnable websites. This paper explains some basic usages of each project, focusing especially on the way Cocoon and Forrest make practical use of XML and XML-related standards.
