XCool is an XQL (XML Query Language) implementation in Java. It consists of an engine which executes queries upon an XML file and can be accessed both programatically and in command line mode. It's not yet fully XQL compliant (doesn't support XML namespaces, methods, and queries containing the root operator), but the goal is to implement the complete XQL functionality.
The Styler Ant Task makes useful combinations of XSLT and other transformations easy to specify in an Ant build file. Styler can handle multiple transformations, in parallel or pipelined, split or merge files, process non-XML files such as HTML (based on JTidy), apply non-XSLT transformation, such as "regular fragmentations" and use any custom XMLReader or XMLFilter class to handle new file formats and transformation techniques.
XMLDB uses an RDBMS to persist arbitrary XML documents. Due to its storage mechanism, searching for and recalling documents is extremely quick. You can also perform XSL translation on documents with surprising speed. The library can be used in any program to store libxml2 documents. A PHP module is also included, making XMLDB into a complete three-tier Web application development suite.
RADpage is a rapid application development system for dynamic, data-driven Web applications. It directly operates inside the browser without requiring a client-dependent development environment. RADpage comes as an Apache module or a CGI, includes a powerful HTML/XML like object-oriented programming language called heitml (pronounced "Hi-TML"), and more than 150 Web application components. Development is done on a fully functional application instead of requiring the edit-save-browse cycle associated with conventional client-side development environments. The RADpage editor stores application pages in readable well-formed XML or upon request in HTML for editing with HTML editors.
SDPXML is an XML parser written in C++ with a clean C++ interface, neither DOM nor SAX. Its functionality includes performing XPath and other queries on a loaded XML document, creating and parsing documents with typesafe conversions between XML and C++ objects, and serializing XML documents to streams. By casting-off the DOM and SAX APIs, SDPXML attempts to provide XML services that integrate well with the rest of the C++ standard library.
UWOBO is a XSLT stylesheet processor running as an HTTP server. In can be contacted with a proper URL which gives the URI of an XML document and a list of stylesheets to be applied. The processor will then apply the stylesheets in the given sequence, and will return the processed document as the result of the invocation.
