You're missing a </tr> after the first row.

I added it in for you, and gave an example of how you can use Hpricot to
load the data. Here is basically everything I know about Hpricot: you can
get the text inside an Hpricot element by passing it #innerHTML, if it is an
element, you can get a list of elements with a specific tag by using
division, for example how I got all the td's from the row. You can get the
first instance of a specific tag by using %, for example how I pull out the
strong.
That is all I know about Hpricot, but it's all a problem like this requires.


require 'rubygems'
require 'hpricot'

rows = Array.new
for row in Hpricot(DATA) % 'table' / 'tr'
  rows.push Array.new
  for data in row / 'td'
    rows.last.push ( data % 'strong' || data ).innerHTML
  end
end

require 'pp'
pp rows

__END__
<table border=1>
  <tr>
    <td>report_data</td>
    <td><strong>liu_asset</strong></td>
    <td><strong> cash</strong></td>
    <td><strong>finance_asset</strong></td>
    <td><strong> note</strong></td>
  </tr>
  <tr>
    <td>2009-12-31</td>
    <td>0 </td>
    <td>1,693,048,000,000</td>
    <td>20,147,000,000</td>
    <td>500</td>
  </tr>

  <tr>
    <td>2009-09-30</td>
    <td>0 </td>
    <td>1,777,512,000,000</td>
    <td>24,977,000,000</td>
    <td>700</td>
  </tr>
</table>
