I would personally use lxml - a quick example:
# -*- coding: utf-8 -*-
import lxml.html
text = """
<tr><td align="center"><b>Sum</b></td><td></td><td align='center'
class="green">245</td><td align='center' class="red">11</td><td
align='center'>0</td><td align='center' >256</td><td align='center' >1.496
[min]</td></tr>
</table>
"""
table = lxml.html.fromstring(text)
for tr in table.xpath('//tr'):
print [ (el.get('class', ''), el.text_content()) for el in
tr.iterfind('td') ]
[('', 'Sum'), ('', ''), ('green', '245'), ('red', '11'), ('', '0'), ('',
'256'), ('', '1.496 [min]')]
It does a reasonable job, but if it doesn't work quite right, then there's a
.fromstring(parser=...) option, and you should be able to pass in ElementSoup
and try your luck from there.
