The SAXON package is a collection of tools for processing XML documents. The main components are: * An XSLT processor, which implements the Version 1.0 XSLT and XPath Recommendations from the World Wide Web Consortium. This version of Saxon also includes some features defined in XSLT 1.1. * A Java library, which supports a similar processing model to XSL, but allows full programming capability, which you need if you want to perform complex processing of the data or to access external services such as a relational database * A slightly improved version of the AElfred parser from Microstar. (But you can use SAXON with any SAX-compliant XML parser if you prefer). Saxon is distributed under the terms of the Mozilla Public License (MPL).
