[closed] .gpx in openlayers

Hi friends, I'm newbie, I'm from Spain, and I want display for example, radars of my country, in a map. I read so much about openstreetmap, and I understand that I need extract radars poi from osm database...I downloaded radars poi from here: http://poi-osm.tucristal.es/ and I obtained a .gpx with the radars of my country...In other hand, I have a basic open layer map, like the .hml of this link: http://wiki.openstreetmap.org/wiki/Openlayers_Track_example This html displays me the map, but how include the radars (the .gpx file) in my openlayer map? I'm here because I'm lost and need help. Regards, Daniel
