Welcome to XML Calabash

XML Calabash is an implementation of XProc: An XML Pipeline Language.

See the XML Calabash project status page for more details.

You can download Calabash and/or read the (very little bit of) documentation. Calabash also ships with the <oXygen/> xml editor (as does Saxon-EE which includes support for validation with W3C XML Schema).

There is a reference guide to XML Calabash.


XML Calabash version 1.1.5 was released on 25 August 2015!

(I changed the stylesheets that generate these pages to be more HTML5-ish. If you have problems in your browser, I'd be curious to hear about it.)
