Based on multiple criterias on parent's siblings

Based on multiple criterias on parent's siblings

I would like to know if I can combine at the same time an XPath looking
for the previous sibling of a certain class with a certain text and at the
same time a sibling at the same level with a certain text.
For example I would like to find the following cells:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160832)">Book</a></td>
by looking up a sibling of class sdawatt_hrdcell containing the text Spin
preceded by a td of class sdawatt_banner with the text Monday - 16
September 2013.
Or the following td:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160864)">Book</a></td>
if we look for the date of the 'Friday - 13 September 2013'.
Is this something doable in Xpath ?
