Xalan-Java http://xml.apache.org/xalan-j/ is an XSLT processor for transforming XML documents into HTML, text, or other XML document types. It implements XSL Transformations (XSLT) Version 1.0 and XML Path Language (XPath) Version 1.0.

Saxon 6.5.5 is an XSLT processor, which implements the Version 1.0 XSLT and XPath with a number of powerful extensions. This version of Saxon also includes many of the new features that were first defined in the XSLT 1.1 working draft, but for conformance and portability reasons these are not available if the stylesheet header specifies version="1.0".

Saxon-B http://saxon.sf.net/ implements the "basic" conformance level for XSLT 2.0 and XQuery. The term basic XSLT 2.0 processor is defined in the draft XSLT 2.0 specifications: it is a conformance level that requires support for all features of the language other than those that involve schema processing.

Saxon 9SA http://www.saxonica.com/ is the schema-aware edition of Saxon 9 and it is one of the built-in processors of <oXygen/>. Saxon SA includes an XML Schema processor, and schema-aware XSLT, XQuery, and XPath processors.

Libxslt http://xmlsoft.org/XSLT/ is the XSLT C library developed for the Gnome project. Libxslt is based on libxml2 the XML C library developed for the Gnome project. It also implements most of the EXSLT set of processor-portable extensions functions and some of Saxon's evaluate and expressions extensions. The libxml2 version included in <oXygen/> is 2.6.32 and the libxslt version is 1.1.23

<oXygen/> uses Libxslt through its command line tool (Xsltproc). The XSLT processor is included into the distribution kit of the stand-alone version for Windows and Mac OS X. Because there are differences between different Linux distributions, on Linux you must install Libxslt on your machine as a separate application and set the PATH variable to contain the Xsltproc executable.

The Xsltproc processor can be configured from the XSLTPROC options page.

Note

Known problem: file paths containing spaces are not handled correctly in the LIBXML processor. For example the built-in XML catalog files of the predefined document types (DocBook, TEI, DITA, etc) are not handled by LIBXML if <oXygen/> is installed in the default location on Windows (C:\Program Files) because the built-in XML catalog files are stored in the frameworks subdirectory of the installation directory which in this case contains at least a space character.

MSXML 3.0/4.0 http://msdn.microsoft.com/xml/ is available only on Windows 2000, Windows NT and Windows XP platforms. It can be used for transformation and validation of XSLT stylesheets .

<oXygen/> use the Microsoft XML parser through its command line tool msxsl.exe

Because msxsl.exe is only a wrapper, Microsoft Core XML Services (MSXML) must be installed on the computer otherwise you get an corresponding warning. You can get the latest Microsoft XML parser from Microsoft web-site http://www.microsoft.com/downloads/details.aspx?FamilyId=3144B72B-B4F2-46DA-B4B6-C5D7485F2B42&displaylang=en

MSXML .NET http://msdn.microsoft.com/xml/ is available only on Windows NT4, Windows 2000 and Windows XP platforms. It can be used for transformation and validation of XSLT stylesheets .

<oXygen/> performs XSLT transformations and validations using .NET Framework's XSLT implementation (System.Xml.Xsl.XslTransform class) through the nxslt command line utility. The nxslt version included in <oXygen/> is 1.6.
