This is a bit of an inception-esque scenario.

I’m trying to parse some data from a CSV using the Rest add-on.
In this addon, to display the data in the template, you use the header cell as the tag.

However, I’m trying to dynamically get the header cells from a Playa tag.
The header cells are URL titles of corresponding entries.

So my template looks something like this:

<table>
  <thead>
    {playa_field}
      <th>{title}</th>
    {/playa_field}
  </thead>
  {exp:rest url="path_to_csv.csv" format="csv"}
  <tr>
    {playa_field}
    <td>{{url_title}}</td>
    {/playa_field}
  </tr>
  {/exp:rest}
</table>

The {{url_title}} is where the issue lies. (Obviously double brackets like that won’t work, it’s just an example).
What I really need is the value of the {url_title} (from the playa tag) to be in its own variable in order to be parsed by the {exp:rest} tag.

So if the {url_title} is “my-entry-title”, I somehow need the tag to be {my-entry-title}.

My CSV would look something like this:

my-entry-title,another-url-title,yet-another-url-title
cell1value,cell2value,cell3value

Hopefully this makes some form of sense to someone.
Thanks!

I got this working by using preload_replace vars, since they are parsed early.

{preload_replace:cell_1="{playa_tag limit='1' offset='0'}{url_title}{/playa_tag}"}
{preload_replace:cell_2="{playa_tag limit='1' offset='1'}{url_title}{/playa_tag}"}
etc

and

{exp:rest ...}
  {{cell_1}}
{/exp:rest}
