Extracting node from highways

I am using overpas turbo to extract nodes from highways(=motorway). Below is the code that I am using. However, this code gives me all the nodes in the bounding box and does not filter the highways.

[out:xml];
(
(way(39.90,32.83,39.96,32.89);)->.a;
((way.a["highway"="motorway"]);)->.b;
((way.a["highway"="motorway_link"]);)->.b;
);
(.b;>;);
out body qt;

One Answer:

You must specify the input set of the recuse down operator as well: .b >;, otherwise it will recuse down the current default input set, which here is set by the outermost union parentheses.

Also: when you set the same output data set twice to the same variable (here: ->.b), the former will be overridden by the latter. If you want to merge the results, you'd have to use an union: (…)->.b;. You can also combine a bbox and a tag query into one statement to get the query more concise: way(<bbox>)[<tag>];. In the end the query you are looking for could look like this: http://overpass-turbo.eu/s/8e0
