Getting de.westnordost.osmapi.common.errors.OsmApiReadResponseException: de.westnordost.osmapi.common.errors.XmlParserException: Error parsing XML at END_TAG </node>@4:164 in java.io.InputStreamReader@1a160b5e when trying to obtain the node

I have a

    MapDataHandler mapDataHandler = new MapDataHandler() {
        public void handle(BoundingBox boundingBox) {
        }

        public void handle(Node node) {
            if (node.getTags().get("highway").equals("bus_stop")) {
            //    System.out.println(node.getTags().get("name"));
            //    System.out.println(node.getTags().get("name:tt"));
            //    System.out.println(node.getTags().get("name:ru"));
            //    System.out.println(node.getTags().get("name:en"));
            }
        }

        public void handle(Way way) {
        }

        public void handle(Relation relation) {
            if (relation.getTags().get("type").equals("route")) {
                if (relation.getTags().get("route").equals("bus")) {
                    System.out.println(relation.getTags().get("name"));
                    busRoutes.put(relation.getTags().get("name"), relation);
                }
            }

        }
    };

When the osm data is processed whti this particular handler I'm getting the following error:

de.westnordost.osmapi.common.errors.OsmApiReadResponseException: de.westnordost.osmapi.common.errors.XmlParserException: Error parsing XML at END_TAG @4:164 in java.io.InputStreamReader@1a160b5e

The exception has nothing to do with your code, it happens earlier - while parsing the XML. It says that the XML returned by the API (you use) is invalid.

It would be helpful to see what call you actually make with your mapDataHandler.

Ok, the call occurs in this cli programm:

I did not ask for your source code. I asked for what HTTP call you actually make.

OsmConnection line 267: What URL cannot be parsed?

By the way, you should really consider using Overpass for things like that. Overpass answers are the same format as OSM Api answers, so you can still use this library for that.

Oh man, what a waste of time. I copy-pasted your code into a new project and executed it, removed your "exception handling" and got the full stack trace.

Note the cause, this is in your code. Elements that do not have tags return null for getTags().
