Supported XSLT Processors

Oxygen XML Editor includes the following XSLT processors:

Xalan 2.7.1 - Xalan-Java 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 - Saxon 6.5.5 is an XSLT processor that 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 9.6.0.7 Home Edition (HE), Professional Edition (PE) - Saxon-HE/PE implements the basic conformance level for XSLT 2.0 / 3.0 and XQuery 1.0. The term basic XSLT 2.0 / 3.0 processor is defined in the draft XSLT 2.0 / 3.0 specifications. It is a conformance level that requires support for all features of the language other than those that involve schema processing. The HE product remains open source, but removes some of the more advanced features that are present in Saxon-PE.
Saxon 9.6.0.7 Enterprise Edition (EE) - Saxon EE is the schema-aware edition of Saxon and it is one of the built-in processors included in Oxygen XML Editor. Saxon EE includes an XML Schema processor, and schema-aware XSLT, XQuery, and XPath processors.
The validation in schema aware transformations is done according to the W3C XML Schema 1.0 or 1.1. This can be configured in Preferences.
Note: Oxygen XML Editor implements a Saxon framework that allows you to create Saxon configuration files. Two templates are available: Saxon collection catalog and Saxon configuration. Both of these templates support content completion, element annotation, and attribute annotation.
Note: Saxon can use the ICU-J localization library (saxon9-icu.jar) to add support for sorting and date/number formatting in a wide variety of languages. This library is not included in the Oxygen XML Editor installation kit. However, Saxon will use the default collation and localization support available in the currently used JRE. To enable this capability follow these steps:
1. Download Saxon 9.6.0.7 Professional Edition (PE) or Enterprise Edition (EE) from http://www.saxonica.com.
2. Unpack the downloaded archive.
3. Create a new XSLT transformation scenario (or edit an existing one). In the XSLT tab, click the Extensions button to open the list of additional libraries used by the transformation process.
4. Click Add and browse to the folder where you unpacked the downloaded archive and choose the saxon9-icu.jar file.
Note that the saxon9-icu.jar should NOT be added to the application library folder because it will conflict with another version of the ICU-J library that comes bundled with Oxygen XML Editor.
Saxon-CE (Client Edition) is Saxonica's implementation of XSLT 2.0 for use on web browsers. Oxygen XML Editor provides support for editing stylesheets that contain Saxon-CE extension functions and instructions. This support improves the validation, content completion, and syntax highlighting.
Note: Saxon-CE, being JavaScript-based, was designed to run inside a web browser. This means that you will use Oxygen XML Editor only for developing the Saxon-CE stylesheet, leaving the execution part to a web browser. See more details about executing such a stylesheet on Saxonica's website.

Note: A specific template, named Saxon-CE stylesheet, is available in the New Document wizard.

Xsltproc (libxslt) - Libxslt 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 expression extensions. The libxml2 version included in Oxygen XML Editor is 2.7.6 and the Libxslt version is 1.1.26.
Oxygen XML Editor uses Libxslt through its command line tool (Xsltproc). The XSLT processor is included in the distribution kit of the stand-alone version for Windows and Mac OS X. Since there are differences between various 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.

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

CAUTION:
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 properly by LIBXML if Oxygen XML Editor is installed in the default location on Windows (C:\Program Files). This is because the built-in XML catalog files are stored in the [OXYGEN_DIR]/frameworks subdirectory of the installation directory, which in this case contains at least a space character.
MSXML 4.0 - MSXML 4.0 is available only on Windows platforms. It can be used for transformation and validation of XSLT stylesheets.
Oxygen XML Editor uses the Microsoft XML parser through its command line tool msxsl.exe.

Since msxsl.exe is only a wrapper, Microsoft Core XML Services (MSXML) must be installed on the computer. Otherwise, you will get a corresponding warning. You can get the latest Microsoft XML parser from Microsoft web-site.
MSXML .NET - MSXML .NET is available only on Windows platforms. It can be used for transformation and validation of XSLT stylesheets.
Oxygen XML Editor 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 XML Editor is 1.6.

You should have the .NET Framework version 1.0 already installed on your system. Otherwise, you will get the following warning: MSXML.NET requires .NET Framework version 1.0 to be installed. Exit code: 128.

You can get the .NET Framework version 1.0 from the Microsoft website.
.NET 1.0 - A transformer based on the System.Xml 1.0 library available in the .NET 1.0 and .NET 1.1 frameworks from Microsoft (http://msdn.microsoft.com/xml/). It is available only on Windows.
You should have the .NET Framework version 1.0 or 1.1 already installed on your system. Otherwise, you will get the following warning: MSXML.NET requires .NET Framework version 1.0 to be installed. Exit code: 128.

You can get the .NET Framework version 1.0 from the Microsoft website.
.NET 2.0 - A transformer based on the System.Xml 2.0 library available in the .NET 2.0 framework from Microsoft. It is available only on Windows.
You should have the .NET Framework version 2.0 already installed on your system. Otherwise, you will get the following warning: MSXML.NET requires .NET Framework version 2.0 to be installed. Exit code: 128.

You can get the .NET Framework version 2.0 from the Microsoft website.
