and amrita is even nicer:

   ~ > cat a.rb
   require 'amrita/template'

   template = Amrita::TemplateText::new <<-html
     <html>
       <head> <title> Woo! </title> </head>
       <body>
         <table>
           <tr id=rows>
             <td id=foo></td>
             <td id=bar></td>
           </tr>
         </table>
       </body>
     </html>
   html

   rows = [
     { :foo => 42,          :bar => 42.0        },
     { :foo => 'forty-two', :bar => 'FORTY-TWO' },
   ]

   template.expand STDOUT, :rows => rows


   ~ > ruby a.rb
   <html>
     <head> <title> Woo! </title> </head>
     <body>
       <table>
         <tr>
           <td>42</td>
           <td>42.0</td>
         </tr><tr>
           <td>forty-two</td>
           <td>FORTY-TWO</td>
         </tr>
       </table>
     </body>
   </html>
