Api returns empty XML

Hello

I am trying to call api for map info:
http://api.openstreetmap.org/api/0.6/map?bbox=47.022588,28.820786,47.025588,28.823786

It return no errors, but xml is empty.

How can I found the reason?

thanks

No the document is not empty. The content is:

<?xml version="1.0" encoding="UTF-8"?>

You will not get nodes, ways or relations as you did not define an area. Your maxlat==minlat and maxlon=minlon, so you defined a point.
