Module: Dcc::Transform::Xslt

Defined in:
lib/dcc/transform/xslt.rb

Overview

Dcc::Transform::Xslt applies an XSLT stylesheet to a DCC XML document.

Nokogiri is OFFICIALLY banned outside validation, so we shell out to the system xsltproc (libxslt) for XSLT 1.0 transforms. For XSLT 2.0/3.0, set ENV["SAXON_JAR"] to point at saxon-he.jar.
