Saxon

saxon.sourceforge.net

One of the most popular and easy-to-use processors available, Saxon is a W3C-compliant processor that comes in two forms: Full Saxon and Instant Saxon. Full Saxon includes Java source code, API documentation, and related resources. Instant Saxon is a Windows executable version (without source code) and is the one you’ll generally want to use.

Saxon includes a wealth of extension functions and elements to supplement the core XSLT language. (See Chapter 16 for more information on extensions.)

Saxon is an Open Source project, which means that its source code is freely available for anyone that conforms to its license agreement.

Available as a Windows executable.

msxsl

msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/02 7/001/766/msdncompositedoc.xml

msxsl does not provide support for extensions at this time. However, because Microsoft is a strong supporter of XML and XSLT technologies, I suspect you will see strong support for msxsl by Microsoft as well as see continued improvements in its capabilities in the future.

Available as a Windows executable.
