Listing XML document canonically

Posted by tom July 13th, 2006

For a project I needed to list for XML documents all it’s nodes in a canonical style. This is how I used Ruby to do it, save the file as listcanonical.rb.


require ‘rubygems’
require ‘xml/libxml’

	
file = ARGV[0]
if file  "" || file  nil 
  puts “Usage: ruby listcanonical.rb ” 
  exit 0
end



	
doc = XML::Document.file(‘response.xml’)
root = doc.root



doc.find(’//*’).each do |node|
  puts node.path
end
