require 'nokogiri'
module Nanoc::Filters
# @since 3.3.0
class XSL < Nanoc::Filter
# Runs the item content through an [XSLT](http://www.w3.org/TR/xslt)
# stylesheet using [Nokogiri](http://nokogiri.org/).
#
# This filter can only be run for layouts, because it will need both the
# XML to convert (= the item content) as well as the XSLT stylesheet (=
# the layout content).
#
# Additional parameters can be passed to the layout call. These parameters
# will be turned into `xsl:param` elements.
#
# @example Invoking the filter as a layout
#
# compile '/reports/*/' do
# layout 'xsl-report'
# end
#
# layout 'xsl-report', :xsl, :awesome => 'definitely'
#
# @param [String] content The XML content to transform
#
# @param [Hash] params The parameters that will be stored in corresponding
# `xsl:param` elements.
#
# @return [String] The transformed content
