JOSM: Searching for negative ID

In a OSM file I have several objects with negative ID (i.e. not yet in OSM database). Is there a way I can search for those IDs? A search for e.g. id:-4 is returns all objects with ID less than or equal to 4, including all with negative ID.

Re: JOSM: Searching for negative ID

Did you try searching with 'new'?

Re: JOSM: Searching for negative ID

Now I did, but searching for "new" will select all objects with negative ID (I presume), so more or less the same as id:-0 (and even id:0, but I don't know why). What I want is to search for the node/way/relation with id -4. The reason for this is that I have a script that identifies potential problems with certain nodes, and prints their (negative) id.

Re: JOSM: Searching for negative ID

You are creating this OSM file yourself? If that's the case, then you can do the following:

assign
odbl=-4 or created_by=-4 or another more descriptive value, of course

Then search for those. It is safe to do this, as those tags will be stripped by JOSM before uploading the data.

Re: JOSM: Searching for negative ID

Thank you for your suggestion! The files I originally indended to search are output from sosi2osm (https://github.com/Gnonthgol/sosi2osm). It may be customized to add such tags. Those files are anyway used as input to further processing and I may as well add a tag there. I just hoped there was a way to do it without rewriting the data.
