Just in case any of you wonder why when you use REXML’s write method on ruby 1.8.6 (2007-09-24 patchlevel 111) [universal-darwin9.0] and possibly other versions, you get errors, it’s a bug in Apple’s REXML library. See this:
def write(writer=$stdout, indent=-1, transitive=false, ie_hack=false) Kernel.warn("#{self.class.name}.write is deprecated. See REXML::Formatters") formatter = if indent > -1 if transitive REXML::Formatters::Transitive.new( indent, ie_hack ) else REXML::Formatters::Pretty.new( indent, ie_hack ) end else REXML::Formatters::Default.new( ie_hack ) end formatter.write( self, output ) end
As you can see, the method sets a local variable of ‘writer’ in the method arguments, however at the bottom it uses ‘output’. A simple change of the bottom line fixes it:
formatter.write( self, writer )
For those who requested it, here’s how to use the formatter:
# I want to create a REXML document to output require "rexml/document" # Make a pretty formatter formatter = REXML::Formatters::Pretty.new( 2 ) # Create some silly xml example xml = REXML::Document.new '<moo>RAR!</moo>' # Write to STDOUT formatter.write( xml, $stdout ) # Write to file xml_file = File.open( "some_file.xml", "a+" ) formatter.write( xml, xml_file )
