Where to download .osm files and how to convert it to .xml? [on hold]

[المشرف العام]

I am new to deal with OSM data, and I want to download only .osm files not .pbf. I tried geofabrik.com but it provides .osm.pbf file format

1. where can I download .osm files?
2. is there any recommended way to convert .osm files to .xml?
