OpenStreetMap. I can't find some objects in XML, which were on the map

I want to get some node (for example, schools, kindergartens) from Planet.osm (http://wiki.openstreetmap.org/wiki/Planet.osm), the snapshot of the OpenStreetMap database. I can see such objects on the map http://www.openstreetmap.org/?lat=59.87326&lon=30.3124&zoom=17&layers=M (school #509, kindergarten #108 and kindergarten #390). But I开发者_JAVA百科 can't find them in the XML file! I got all objects (s), which have Latitude > 59.86 and Latitude < 59.88 and Longitude > 30.31 and Longitude < 30.32 (this part of map). I've got 42 objects, but I couldn't find school #509, kindergarten #108 and kindergartens #390 and so on. Why?

Are the information on the map and in the XML file quite different? Why I can't find map's object in the XML file?

Maybe you are using an old planet.osm? Using the openstreetmap api directly the nodes you search for appear as they should.
