How to filter relation members in Overpass

Question

My final goal is to get country borders from OSM via Overpass API. I know my country's relation object id - http://www.openstreetmap.org/relation/59065 - and can get its details with the following query:

[out:json];
  rel(59065);
out body;

The relation members list contains ways (which comprise the country border) as well as some other nodes and relations. How can I filter relation members to leave only way elements?

Answer 1

You cannot reduce the output of the relation itself (it will always include all elements). However, you can specify to only return ways, which are included in a relation:

[out:json];
rel(59065);
way(r);
out geom;
