Editing XSL (section)

== The XSL family ==

=== XSL Transformations ===
{{main|XSLT}}

The original version of XSLT (1.0) was published in November 1999, and was widely implemented. Some of the early implementations have fallen into disuse, but notable implementations
actively used in 2023 include those integrated into the mainstream [[web browser]]s, as well as [[Altova]]'s RaptorXML, [[libxslt]], [[Saxon XSLT|Saxon]], the [[Microsoft]] [[.NET]] implementation '''System.Xml.Xsl''', and [[Xalan]] which is integrated into the Oracle [[JVM]]. These products all have a high level of conformance to the specification, though they also offer proprietary vendor extensions, and some of them omit support for optional features such as disable-output-escaping.

Subsequent versions of XSLT include XSLT 2.0 (January 2007) and XSLT 3.0 (June 2017); there is work in progress on a version 4.0. These versions have not been as widely implemented as 1.0: the main implementations in widespread use in 2023 are [[Saxon XSLT|Saxon]] (available in various versions for different platforms, including web browsers), and [[Altova]]'s RaptorXML.

=== XSL Formatting Objects ===
{{main|XSL Formatting Objects}}

Support for XSL Formatting Objects is available in a number of products:

* the [[XEP (software)|XEP]] package from [[RenderX]] has near 100% support for XSL-FO 1.0
* XSLFormatter from Antenna House also has near 100% support for the XSL-FO 1.0 specification and has 100% support for all new features within the XSL-FO 1.1 specification
* XINC from Lunasil has a great amount of support for the XSL-FO 1.0 specification
* [[Formatting Objects Processor|FOP]] from the [[Apache Software Foundation|Apache]] project can render a portion of the XSL formatting objects 1.0 specification to [[Portable Document Format|PDF]]
* XML2PDF Formatting Engine Server from AltSoft has near 100% support for the XSL-FO 1.1

These products support output in a number of [[file format]]s, to varying degrees:

* [[Portable Document Format]]
* [[PostScript]]
* [[Scalable Vector Graphics|SVG]]
* [[Maker Interchange Format|MIF]]
* [[Printer Control Language|PCL]]
* [[text file]]s

=== XPath ===
{{main|XPath}}

XML Path Language ([[XPath]]), itself part of the XSL family, functions within [[XSLT]] as a means of navigating an XML document.

Another [[W3C]] project, [[XQuery]], aims to provide similar capabilities for querying XML documents using [[XPath]].
