XSLT is the abbreviation for Extensible Stylesheet Language Transformations. It is one of two parts of the " title="Extensible stylesheet language">XSL specification and is a language for transforming " title="XML">XML documents (actually the transformation part, T stands for transformation).
XSLT is a " title="XML transformation language">XML transformation language, which transforms documents in " title="XML">XML format. To transform in this context means to take all data or part of it (Query of a selection with " title="XPath">XPath) and create another XML document or a document in a format which can directly be used for displaying or printing (e.g. an " title="HTML">HTML, " title="RTF">RTF or " title="TeX">TeX document). In particular the transformations involve:
- adding constant text like HTML document type and header information
- moving text
- sorting text
The XSLT processor checks which rules can be applied and executes the associated transformations based on a sequence of priorities.
An XSLT program is an XML document as the following template shows
<?xml version="1.0" ?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> ...
