New Responsive Form - Display data from repeating section list form into repeating section task form

Currently you need to use Query XML for each control in the Repeating Section to populate the same number of Collections.

Then do a "For Each" loop to extract an item from the first collection and set the Output index.

Within the loop do a whole series of "Get Item from Collection" to extract each item from the remaining collections. (using the Output index value from the For Each loop).

Also within the loop (after all the get items above) do a Build String to concatenate an HTML formatted string with the next group of freshly extracted items of the current row in the Repeating Section. At minimum the string could be like this:
{Variable: html rptsection}<div>- 1st control description {Variable:txt 1st extraction}, 2nd control description {Variable:txt 2nd extraction}</div>
The Output in this case would be the text variable html rptsection

Now in your Task Form use a Text - Long control with the Text Format of Rich Text selected and connect it with the html rptsection variable.

If this help solve your challenge then please mark this as a solution.

I have tried to use the ID from the XML. It sill does not populate the data. But one thing i have realise is the connection from task form reapeating section to the 
XML column is fine, because it able to show same number of field in the repeating section. No, the problem is what is the correct ID for the controls.

It's true that natively this is a current limitation, however, my original post details a functional work-around that builds an HTML string and populates it within a Rich Text enabled Text-Long control.

I have tried with export and import of original form but it didn't work for me. Though, I am getting the exact number of rows in the repeating section as it connected to the multiline column.
