>>> from BeautifulSoup import BeautifulSoup
>>> bs = BeautifulSoup("""<td> </td>
...
... <td width="1%" class=key>Open:
... </td>
... <td width="1%" class=val>5.50
... </td>
... <td> </td>
... <td width="1%" class=key>Mkt Cap:
... </td>
... <td width="1%" class=val>6.92M
... </td>
... <td> </td>
... <td width="1%" class=key>P/E:
... </td>
... <td width="1%" class=val>21.99
... </td>
... """)
>>> for key in bs.findAll(attrs={"class": "key"}):
...     value = key.findNext(attrs={"class": "val"})
...     print key.string.strip(), "-->", value.string.strip()
...
Open: --> 5.50
Mkt Cap: --> 6.92M
P/E: --> 21.99
