Xpath match current node or one of child nodes -


i'm having trouble creating xpath following html:

<html> <body> <table class="tablesorter"> <tbody>          <tr class="tr_class">                     <td>{some td info}</td>                     <td>{some td info}</td>                                         <td>                         <span class="span1">                             <span class="span2">out</span>                             <span class="span3">smth</span>                             <span class="span4">out</span>                         </span>                     </td>        </tr>      <tr class="tr_class">                     <td>{some td info}</td>                     <td>{some td info}</td>                                         <td>in</td>      </tr>      <tr class="tr_class">                     <td>{some td info}</td>                     <td>{some td info}</td>                                         <td>in</td>      </tr>     </tbody> </table> </body> </html>

what want create xpath return me content of each third td node (if doesn't have children) or content of it's span has class="span2". example, html should return

out,in,in

i have xpath return needed span node, looks like:

//table[@class = 'tablesorter']//td[3]/descendant::*[@class='span2']/text()

and have xpath return me simple content of each 3d td nodes:

//table[@class = 'tablesorter']//td[3][count(descendant::*)=0]/text()

but need 1 xpath, because me necessary have right ordering of 'in' or 'out' values (their ordering in table)

this it, no idea how robust "corpus":

//table[@class="tablesorter"]/tbody/tr/td[3]/descendant::text()[normalize-space(.)!=""]

['out', 'in', 'in']

update

//table[@class="tablesorter"]/tbody/tr/td[3]/descendant::text()[normalize-space(.)!=""][parent::td or parent::span[@class="span2"]]
