Saxon-CE product information


On this page:

Note: Saxon-CE is no longer in development. As of 2017, the product has been superseded by Saxon-JS, the XSLT 3.0 run-time in JavaScript.

Saxon-CE (Client Edition) is Saxonica's implementation of XSLT 2.0 for use on web browsers.

The current release is Saxon-CE 1.1 (released 22 February 2013).

Unlike previous releases, Saxon-CE 1.1 is open-source software.

Product information

Information about the general capabilities of the product, as well as detailed instructions for installing the product and writing applications, can be found in the documentation (for Javascript users, this is presented using a Saxon-CE browser application: it will take a few seconds to load the first time you use it).

A number of Saxon-CE users have built proof of concept demonstrations which use the Saxon-CE software.

The product is open-source. The primary license is the Mozilla Public License version 2.0. In most cases, the source files are marked as being "incompatible with secondary licenses", which means that the code cannot be combined with code issued under a GPL license (the reason for this is the difficulty of contacting all past contributors to gain their assent).

Some components are licensed under the Apache version 2.0 license or under BSD-style licenses. For more information on licensing, see Licenses.

Saxon-CE is issued in the form of compressed Javascript code that is mounted on your web server to be fetched and executed from HTML pages running in a web browser. There are no server-side executables, and therefore no dependencies on your server configuration. The software works with all modern web browsers provided Javascript is not disabled.

The software is issued as a zip file that you will first need to unzip into your chosen location (the relevant section of your web server filestore). See the Installing the Software page of the documentation for more detail.

Sample applications

The documentation is presented using a Saxon-CE stylesheet, so this represents one sample application that you might wish to study. A description on how it works can be found in our XML Prague 2013 conference paper. You will find the main stylesheet at cetree.xsl.

Other sample applications are described in the documentation.

Source code

Source code and build files can be found in the Saxon-CE github repository.

To build the product, you will need to download GWT 2.5.

The github repository also holds master documentation, sample applications, and other resources. It currently contains very little test material, but we intend to add this in due course.

If you are interested in becoming a project committer, please contact Saxonica. We will need you (and possibly your employer) to sign a contributor agreement, and we will exercise very strict quality control over any contributions we accept.
