STX

STX is an XML transformation tool based on XSLT and Scheme which combines a processor for most common XSLT stylesheets and a framework for their extension in Scheme and provides an environment for a general-purpose transformation of XML data. It integrates two functional languages - Scheme and XSLT-like transformation language on the basis of the common data model - SXML.
