data (iterable, Osm or Element) – source data
query (func) – function to apply to each element and returns a
boolean deciding if it will be included or not
Ejemplo
>>> d1 = osm.Osm()
>>> n1 = d1.Node(1, 1, tags={'tourism': 'viewpoint'})
>>> n2 = d1.Node(2, 2, tags={'amenity': 'cafe'})
>>> d2 = osm.Osm()
>>> d2.append(d1) # all
>>> d3 = osm.Osm()
>>> d3.append(d1, lambda e: 'amenity' in e.tags) # only amenities
