After corresponding with RXP's author, this is what I
am currently using to validate my HTML without a network
connection:

  htmlfiles.each do |file|
   result = `rxp -sD html file://html-v4.01-strict.dtd #{file} 2>&1`
   $stderr.puts result if result.empty?
  end

Note: the lame '2>&1' hack to capture standard error.

To be more general, I'd remove the -D mess and make a XML
catalog of local DTDs and point to it with the XML_CATALOG_FILES
environment variable.  An example catalog is available at
