Oh I see! Sorry for the confusion, and thanks again. Following your 
hints I got it working! Below is my code in case this is useful for 
someone struggling with the same problem. Beware, the regex is probably 
VERY naive!

:-) Ingo




class CustomRedCloth < RedCloth

  RULES = [:inline_textile_geo, :inline_textile_span, 
:inline_textile_link, :block_textile_lists, :block_textile_prefix ]

  # render 'geo' microformat (abbr pattern)
  def inline_textile_geo( text )
    # this: "content":-71.34534/22.34760
    text.gsub!( /"([^"]+)":(-?\d+\.\d+)\/(-?\d+\.\d+)/ ) do |m|
        content,lat,lng = $~[1..3]
        # becomes this: <abbr class="geo" 
title="-71.34534;22.34760">content</abbr>
        "<abbr class=\"geo\" title=\"#{lat};#{lng}\">#{content}</abbr>"
    end
  end

  def to_html
    super(*RULES)
  end

end
