Overpass-turbo query for towns up to capital=7 and their admin_level=6 parents name

Question

I'm trying to output a file in Overpass Turbo, let's assume CSV (because it seems easier to accomplish this with CSV), with:

All nodes in Portugal where the tag capital=yes or capital=1 or (...) or capital=7
For all those nodes, output the following information: name (tag), capital (tag) and coordinates and find the rel with the tag border_type=distrito (or admin_level=6) they belong to, and output it's name as well.

Example output:

name	capital	lat	lng	parent
City_1	7	38.123	-9.123	County_1
City_2	2	38.123	-9.123	County_1
City_3	4	38.123	-9.123	County_2
City_4	4	38.123	-9.123	County_3
City_5	4	38.123	-9.123	County_2

I've managed to output all info correctly except for the parent information, with this Overpass Turbo query:

[out:csv(name,capital,::lat,::lon;true;";")][timeout:250];
{{geocodeArea:Portugal}}->.searchArea;

(
  node["capital"="yes"](area.searchArea);
  node["capital"="1"](area.searchArea);
  node["capital"="2"](area.searchArea);
  node["capital"="3"](area.searchArea);
  node["capital"="4"](area.searchArea);
  node["capital"="5"](area.searchArea);
  node["capital"="6"](area.searchArea);
  node["capital"="7"](area.searchArea);
);

out body;
>;
out skel qt;

However, I'm having a hard time figuring out how to get which admin_level=6 each place belongs to. Any help would be greatly appreciated.

Unsure if it's possible, but try looking at recursion (to get the relation on the way) & the 'for' block command in the wiki & here: https://dev.overpass-api.de/blog/index.html (unfortunately it's isn't searchable. you'll have to go through each page individually)

Compacted version of your routine using RegEx:

[out:csv(name,capital,::lat,::lon;true;";")];
{{geocodeArea:Portugal}};
node[capital~"yes|[1-7]"](area);
out meta;
