<tr class="pointer" onmouseover="this.style.cursor='hand'" title="perform" style=""> <td onclick="javascript:__dopostback">perform operation roll no. 150</td> <td onclick="javascript:__dopostback">07 jul 2015 05:26 pm</td>   <tr class="pointer" onmouseover="this.style.cursor='hand'" title="perform" style=""> <td onclick="javascript:__dopostback">perform operation roll no. 161</td> <td onclick="javascript:__dopostback">07 jul 2015 05:18 pm</td>   <tr class="pointer" onmouseover="this.style.cursor='hand'" title="perform" style=""> <td onclick="javascript:__dopostback">perform operation roll no. 155</td> <td onclick="javascript:__dopostback">07 jul 2015 05:13 pm</td> 

note xpath not working , below table changes.

please try below xpath:

//td[contains(text(),'roll no. 161')] 

this locate td element has innerhtml/text roll no. 161. can replace 161 other roll number want locate.

or

in case want click on 2nd, 3rd or other td element respect text roll no. on list, can try these:

• (//td[contains(text(),'roll no.')])[2]

this locate 2nd td element in chronological order of dom representation contains innerhtml/text roll no..

• (//td[contains(text(),'roll no.')])[3]

this locate 3rd td element in chronological order of dom representation contains innerhtml/text roll no..

similarly, can replace last [2] other number locate concerned element in page.
