XSLT powers Symphony's page templates and utilities, which together comprise the templating layer.
XSLT is a rule-based language used to transform XML. XSLT powers Symphony’s templating layer, enabling users to write modular, dynamic templates while maintaining complete control over the resulting output. A Symphony project’s page templates and utilities are XSLT stylesheets.
XSLT is used in Symphony's page templates and utilities.

XSLT relies on XPath to select nodes in an XML source and to perform complex matching and calculations.
XSLT is a widely-adopted open standard recommended by the W3C.
Symphony uses PHP's libxslt extension for XSLT processing. At this time, libxslt only supports XSLT 1.0.
