Overpass API : Sorted list of stations of a relation

Hi, I'm pretty new a OSM & the Overpass API.

I was looking for, how to retrieve a list a stations of a given relation.

Here is what came up with :

< id-query ref="2418275" type="relation" />
  < recurse type="relation-node" />  
< print/>

It works great but the station nodes are sorted by IDs in the XML. I was looking to get them sorted by the orientation (first station as first element, last station as last element).

Do you know how can I can achieve this ?

One Answer:

Unfortunately, this is currently not possible with the Overpass API alone. What you can do is print the relation also and then sort the stations in a post-processing step.

Ok thanks, I went with a bash script to do this :

for i in curl 'http://api.openstreetmap.org/api/0.6/relation/2418275' | grep stop | awk '{print $3}' | cut -d '"' -f2; do curl http://api.openstreetmap.org/api/0.6/node/${i} ; done`
