... </ul>
... '''
>>> 
>>> soup = BeautifulSoup(html)
>>> spans = [x.text.strip() for x in soup.select('ul.important-fields li span')]
>>> strongs = [x.text.strip() for x in soup.select('ul.important-fields li strong')]

>>> spans
[u'Agency Fees:', u'Bedrooms:', u'Bathrooms:']
>>> strongs
[u'AED 5000', u'Studio', u'1']

>>> for name, value in zip(spans, strongs):
