I need to add a new class to a td (the first in the code below), but with two conditions: only if that td has a specific number on it (for example “2”), and if the next td also has some text on it (for example “6oz”).

The need to add this new class, is because I will use it to count the total of units that meet the conditions mentioned above. (2 and 6oz for example)

I have a big limitation, I have several tr in the code, and I can not modify the initial code, so it won’t be possible to identify the tr (in the code below).

Thanks in advance for any help!! I’ll really appreciate your advice.

<tr>
  <td class="a-text-center">2</td>
  <td class="a-text-left">
      <span class="a-text-bold">bottle 6oz</span> <br>
      <div class="a-row"> 
        <span class="a-text-bold"> Condition: </span> <span> New </span> 
      </div></td>
</tr>
