Check out scRUBYt!:

Quick example:

Input

=================================================================
<html>
   <body>
     <table border=1 padding=10>
       <tr>
         <td>1</td>
         <td>2</td>
       </tr>
       <tr>
         <td>3</td>
         <td>4</td>
         <td>5</td>
       </tr>
     </table>
     <br/>
     <table border=1 padding=10>
       <tr>
         <td>6</td>
       </tr>
       <tr>
         <td>7</td>
       </tr>
       <tr>
         <td>8</td>
       </tr>
     </table>
     <br>
     <table border=1 padding=10>
       <tr>
         <td>9</td>
  <td>10</td>
       </tr>
       <tr>
       </tr>
       <tr>
         <td>11</td>
       </tr>
     </table>
   </body>
</html>

scRUBYt program to extract all the cells:

=================================================================
table_data = Scrubyt::Extractor.define do

     fetch "input.html"

     cell '1'
end

output:

=================================================================
   <root>
     <cell>1</cell>
     <cell>2</cell>
     <cell>3</cell>
     <cell>4</cell>
     <cell>5</cell>
     <cell>6</cell>
     <cell>7</cell>
     <cell>8</cell>
     <cell>9</cell>
     <cell>10</cell>
     <cell>11</cell>
   </root>
