Post-process a Web site to "tidy" all the pages' HTML.

tidy_site.rb

=begin
Initial Setup (run once at the command prompt, as an admin user).

First, check your environment with

  gem env
  
If you get an error at this point, it is likely you don't have
rubygems installed, and you should do that. The easiest way to
get it all ready to go at once is to install RVM. Instructions 
are at http://rvm.io

If you have RVM (and you will know if you do)

  gem install nokogiri-pretty

If you don't (just using the System ruby on your Mac)

  sudo gem install nokogiri-pretty

Any errors at this point will be instructional in
getting the script to work -- don't ignore them!

To Use:

Call this script like this (from the same 
folder where you saved it):

ruby ./tidy_site.rb /path/to/the/site

If your path includes any spaces, be sure to 
surround the path with double-quotes:

ruby ./tidy_site.rb "/Users/waltd/Documents/Project Name/Site Folder"

=end

require 'rubygems'
require 'fileutils'
require 'nokogiri-pretty'

base = ARGV[0].chomp
if( ! File.exists? base )
  puts 'Missing Site Folder!'
else
  Dir.glob( File.join(base, '**/*.html')).each do | page |
    doc = Nokogiri::XML(File.read(page))
    clean = doc.human.sub('<?xml version="1.0" encoding="UTF-8"?>', '').strip
    File.open(page, 'w') {|f| f.write(clean) }
  end
  puts "#{base} site processed!"
end
