It works for me:


In [1]: from BeautifulSoup import BeautifulSoup as bs

In [2]: soup=bs('''<tr>
    ...: <td>WY</td>
    ...: <td>Wyo.</td>
    ...: <td><a href="/wiki/Wyoming" title="Wyoming">Wyoming</a></td>
    ...: <td><a href="/wiki/Cheyenne%2C_Wyoming" title="Cheyenne,
    ...: Wyoming">Cheyenne</a></td>
    ...: <td><a href="/wiki/Cheyenne%2C_Wyoming" title="Cheyenne,
    ...: Wyoming">Cheyenne</a></td>
    ...: <td><a href="/wiki/Image:Flag_of_Wyoming.svg" class="image" 
title=""><img
    ...: 
src="http://upload.wikimedia.org/wikipedia/commons/thumb/b/bc/Flag_of_Wyomin
    ...: g.svg/45px-Flag_of_Wyoming.svg.png" width="45" alt="" height="30"
    ...: longdesc="/wiki/Image:Flag_of_Wyoming.svg" /></a></td>
    ...: </tr>
    ...: </table> '''
    ...:
    ...:
    ...:
    ...: )

In [18]: rows=soup('tr')

In [19]: rows
Out[19]:
[<tr>
<td>WY</td>
<td>Wyo.</td>
<td><a href="/wiki/Wyoming" title="Wyoming">Wyoming</a></td>
<td><a href="/wiki/Cheyenne%2C_Wyoming" title="Cheyenne,
Wyoming">Cheyenne</a></td>

title=""><img src="http://upload.

g.svg/45px-Flag_of_Wyoming.svg.png" width="45" alt="" height="30" 
longdesc="/wiki/Image:Flag_
</tr>]

In [21]: cells=rows[0]('td')

In [22]: cells
Out[22]:
[<td>WY</td>,
  <td>Wyo.</td>,
  <td><a href="/wiki/Wyoming" title="Wyoming">Wyoming</a></td>,
  <td><a href="/wiki/Cheyenne%2C_Wyoming" title="Cheyenne,

In [23]: cells[0].string
Out[23]: 'WY'

In [24]: cells[2].a.string
Out[24]: 'Wyoming'

In [25]: cells[3].a.string
