Return both selector & click selector values in one row

How to?
#1

Hello everyone,
I'm trying to scrape some values from all the <tr> elements (in this example below .display and .desc).

I'm using the Click Selector for the 3rd <tr> element in the example.
Is there a way to group both selector & click selector values in one row?
In the example below both the clicked <tr> and its newly appeared sibling in one chunk containing .display (from the clicked element) and .desc (from the one that just appeared)?

 <tr class="item expandable">
   <td><span class="display">07.08.</span></td>
   <td class="desc">I need to scrape this</span></td>

   <td class="amount">
      <fin-amount>-57.00</fin-amount>
      <span class="currency"></span>
   </td>
</tr>

/*****************/
<tr class="item expandable">
   <td><span class="display">07.08.</span></td>
   <td class="desc">
   	
   		NOT the actual value I need to get
   	
   	</td>
   <td class="amount">
      <fin-amount>-57.00</fin-amount>
      <span class="currency">USD</span>
   </td>
</tr>
/* This will reveal itself upon clicking on the previous <tr> */
<tr class="item expandable detail">
	   <td class="desc">
	 
	   I need to scrape this along with some values of the previous TR sibling

	 	</td>
</tr>
/****************/


<tr class="item expandable">
   <td><span class="display">07.08.</span></td>
   <td class="desc">I need to scrape this</span></td>

   <td class="amount">
      <fin-amount>-57.00</fin-amount>
      <span class="currency"></span>
   </td>
</tr>

Thanks in advance
