XSL
In computing, the term Extensible Stylesheet Language (XSL) is used to refer to a family of languages used to transform and render XML documents (e.g., XSL is used to determine how to display a XML document as a webpage). Historically, the W3C XSL Working Group produced a draft specification under the name "XSL", which eventually split into three parts: XSL Transformation (XSLT): an XML language for transforming XML documents XSL Formatting Objects (XSL-FO): an XML language for specifying the visual formatting of an XML document XML Path Language (XPath): a non-XML language used by XSLT, and also available for use in non-XSLT contexts, for addressing the parts of an XML document.
