I've not used CGI much myself, but a quick experiment yielded this:

	require 'cgi'

	cgi = CGI.new('html4')
	html = cgi.html do
	  cgi.body do
	    cgi.pre do
	      "Don't use 'out'"
	    end
	  end
	end

	# Now you can do what you want with it, for example:
	puts CGI.pretty(html.gsub(/<([^!][^>]*)>/) { "<#{$1.downcase}>" })

Outputs:

	<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"  
"http://www.w3.org/TR/html4/strict.dtd">
	<html>
	  <body>
	    <pre>
	      Don't use 'out'
	    </pre>
	  </body>
	</html>

I don't know if it's the best tool for your task, but anyway I hope that  
helps...
