Parse the resulting file extracting node IDs, and add lines similar to "<node id=<nodeid> lat='0' lon='0' visible='false' />" to the beginning of the file... If you want to/can use JOSM to remove them, when complete, add back the <?xml and <osm> tag at the top, the </osm> tag at the bottom and replace all instances of visible='true' with visible='false', load into JOSM and hit upload... Otherwise, you'll probably need to use the bulk import script, for this, you'd add <?xml, <osmChange and <delete tags at the top and </delete> and </osmChange> at the bottom, then feed it through the bulk import script... I hope that helps... It's quite easily scriptable, though perhaps someone has a premade bulk-delete script already... d
