Guardfile (https://github.com/guard/guard) to monitor docx files in the current directory and, when changed, extract the document.xml from the changed docx file to the current directory. This is helpful when you want to see how a change made to a docx file changes the underlying xml.

Guardfile

require 'zip/zip'
require 'xmlsimple'
require 'guard/guard'

# monitor docs directory
module ::Guard
  class Docx < Guard
    def run_on_changes(paths)
      paths.each do |path|
        #puts File.expand_path(path)
        new_info = extract_information(path)
        File.open("#{path}.xml", "w") {|f| f.write new_info}
      end
    end

    def extract_information(path)
      zipped = Zip::ZipFile.open(File.expand_path(path))
      xml_data = zipped.read('word/document.xml')
      xml_hash = XmlSimple.xml_in(xml_data)
      return XmlSimple.xml_out(xml_hash)
    end
  end
end

guard 'docx' do
  watch(%r{\A[^\$]*\.docx\z})
