This seems to work well:

@html.scan(/~\^LNK:.*?\^~/mi).each do |link_line|
  new_link_line = link_line.gsub(/[\t\r\n]/, '')
  @html.gsub!(/#{Regexp.escape(link_line)}/mi, new_link_line) if 
link_line != new_link_line
end

I wonder if I could have done with with one @html.gsub!() command, but 
this is much more understandable to me anyway so I'll stick with this.

Thanks,
Wes
