EXAMPLES

Simple example

  require 'xml/xslt'

  xslt = XML::XSLT.new()
  xslt.xml = "text.xml"
  xslt.xsl = "test.xsl"

  out = xslt.serve()
  print out;

REXML support

  require 'rexml/document'
  require 'xml/xslt'

  xslt = XML::XSLT.new()

  xslt.xml = REXML::Document.new File.read( "test.xml" )
  xslt.xsl = REXML::Document.new File.read( "test.xsl" )

  out = xslt.serve()
  print out;

XML::Smart support

  require 'xml/smart'
  require 'xml/xslt'

  xslt = XML::XSLT.new()

  xslt.xml = XML::Smart.open( "test.xml" )
  xslt.xsl = XML::Smart.open( "test.xsl" )

  out = xslt.serve()
  print out;

Parameters support

  require "xml/xslt"

  xslt = XML::XSLT.new()
  xslt.xsl = "parameter.xsl"
  xslt.xml = "test.xml"
  xslt.parameters = { "p1" => "the first parameter ...",
                      "p2" => "'and the second one!'" }
  xslt.save("test1.html")

  xslt.parameters = { "p1" => "Ruby...",
                      "p2" => "'...is cool !'" }
  xslt.save("test2.html")

External functions support

  require "xml/xslt"

  xslt = XML::XSLT.new()
  xslt.xsl = "functions.xsl"
  xslt.xml = "test.xml"

  XML::XSLT.registerExtFunc("http://test.none", "round-trip") do |arg|
    arg
  end

  XML::XSLT.registerExtFunc("http://test.none", "type") do |arg|
    arg.class.to_s
  end

  print xslt.serve

Error handling

  XML::XSLT.registerErrorHandler { |string| puts string }

  xslt = XML::XSLT.new
  xslt.xml = "not xml"

This fragment would print:

  Entity: line 1:
  parser
  error :
  Start Tag expected, '<' not found
  not xml
  ^
