This section lists some Saxon add-ons and extensions produced by third parties. Saxonica Limited takes no responsibility for the quality of these products.
Open Source tools
Kernow is a graphical front-end for Saxon. This is an open-source product developed by Andrew Welch. It provides an effective alternative to the Saxon command line interface for users who prefer a GUI for running ad-hoc transformations. This tool was last updated in 2015: we would welcome feedback as to whether it still works with current Saxon releases.
You can experiment with evaluation of XSLT stylesheets under Saxon (and other XSLT processors) at https://xsltfiddle.liberty-development.net/.
XSpec is an open-source framework for running XSLT and XQuery unit tests, including features like performance profiling and code coverage. It has an active developer and user community, and works with both open-source and commercial Saxon editions.
XMLResolver.org provides implementations of callbacks (
XmlResolver etc) on both Java and C#, that enable resources identified
by URI to be retrieved from a local cache, by reference to a resource catalog. The library can be used with
Saxon on both the Java and C# platforms. The lead
developer, Norm Walsh, is now with Saxonica, and Saxonica supports his continued involvement in the project.
Schematron is a language for specifying assertions about XML documents; it has a wide range of uses both in conjunction with, and as an alternative to, the XSD schema specification. Both the original implementation by Rick Jeliffe, and the more recent implementation by David Maus (SchXslt), rely heavily on Saxon "under the hood".
Commercial Editors and Debuggers
A number of commercial XML IDEs provide support for XML, XSLT, and/or XQuery editing and debugging, with the ability to configure Saxon as the chosen XSLT/XQuery processor. These include:
Stylus Studio: offers XSLT, XQuery, and XML Schema development and debugging, all using Saxon. It has Saxon-EE built-in (but you will need a separate license to run Saxon-EE applications outside the IDE).
Oxygen XML Editor offers XSLT and XML Schema development and debugging for Saxon. It has Saxon-EE built-in (but you will need a separate license to run Saxon-EE applications outside the IDE).
A budget XML Editor and Debugger for Saxon is EditiX.
XML Spy from Altova allows you to configure Saxon as your XSLT or XQuery processor, but does not provide Saxon debugging. If you want to run Saxon-PE or -EE, you will need your own license. There is also a third-party plug-in that allows Saxon-EE to be used for schema validation.
