Web and XML Glossary

XSP is Cocoon's technology for building WWW applications based on dynamic XML content. An XSP page is a Cocoon XML document containing tag-based directives that specify how to generate dynamic content at request time. Upon Cocoon processing, these directives are replaced by generated content so that the resulting, augmented XML document can be subject to further processing (typically an XSLT transformation). XSP pages are transformed into Cocoon producers, typically as Java classes, though any scripting language for which a Java-based processor exists could also be used. Directives can be either XSP built-in processing tags or user-defined library tags. XSP built-in tags are used to embed procedural logic, substitute expressions and dynamically build XML nodes. User-defined library tags act as templates that dictate how program code is generated from information encoded in each dynamic tag.
