Loading an XML file into UE4Editor

Hello all

I am currently trying to make this street map plugin for UE work on my machine.

I have managed to get a version that works with 4.20 but I cannot seem to be able to import XML files as recommended on the “how to use the plugin” guidelines. UE4Editor tells me that the extension .xml is unknown and that I cannot import it.

Is there anything I could do about it?

So the problem really just seems to be with the .xml extension. Renaming with the command line the files to .osm only solved the problem.
