Extract nodes from way

Question

Hi, I have an 'way id' of my route. I want to extract all nodes which belongs to this specific route. I can make a query e.g.: http://api.openstreetmap.org/api/0.6/way/xxxyyzz In response I receive series of node reference id's. Then I need to make recursive lookup to search each single point to get GPS data. Do you know automatic tool to extract such data? I will provide way_id and in response get series of GPS coordinates. It is fair easy to write such tool but maybe you know readily available software.

Accepted Answer

There is an API request that returns the way and all its nodes:

http://api.openstreetmap.org/api/0.6/way/xxxyyzz/full

Answer 2

You can download http://api.openstreetmap.org/api/0.6/way/xxxyyzz/full instead of http://api.openstreetmap.org/api/0.6/way/xxxyyzz/. This will contain all the nodes that are in this way, thus avoiding the need for further queries.

You can use something like

wget -q -O - http://api.openstreetmap.org/api/0.6/way/xxxyyzz/full | sed -ne 's/<node.*lat="\(.*\)" lon="\(.*\)" version.*/\1 \2/p'

to limit output to the latitude and longitude of the node. (And yes I know that parsing XML with regex is evil.)
