xmlizer configurator/server is a client/server approach for custom database to XML mapping. The configurator is used to set up projects and the server delivers the processed requests on demand (like a Web server) according to the mapping rules made with the configurator, which includes a drag and drop GUI. One module is for dumping databases (or parts of it) in a fixed format and the other module can build XML instances satisfying a specified XML Schema (or DTD).
The goal of xmlportlet is to provide a base portlet to serve as a simple mechanism for transforming XML data into the view for your portlet application. This base portlet will be JSR-168 compliant, and will relieve you from developing the basic boilerplate logic needed to transform XML using XSLT into HTML.
xmlroff is a fast, multilingual, multi-platform XSL formatter that transforms XSL-FO documents (or any XML with an appropriate XSL stylesheet) into PDF or PostScript. It aims to excel at DocBook formatting, and it integrates easily with other programs and with scripting languages.
xmlrpcserver is a simple to use but fairly complete XML-RPC server module for Python, implemented on top of the standard module xmlrpclib.
