I'm confused, I don't recognise this output and its formatting.
The ogrinfo output looks like this:

OGRFeature(TrackLog):463
  LATITUDE (Real) =      52.2347283333
  LONGITUDE (Real) =      21.0829150000
  ALTITUDE (Real) =         162.500
  EASTING (Real) =          21.083
  NORTHING (Real) =          52.235
  UTCDATE (Date) = 2008/02/14
  UTCTIME (String) = 001121
  SOG (Real) =    4.9
  COG (Real) = 273.6
  MAG_VAR (Real) =   0.0
  SATS_USED (Integer) = 5
  HPE (Real) = (null)
  VPE (Real) = (null)
  EPE (Real) = (null)
  HDOP (Real) =    1.7
  VDOP (Real) =    2.9
  PDOP (Real) =    3.4
  QUALITY (Integer) = 1
  DIFF_AGE (Real) = (null)
  DIFF_ID (Integer) = (null)
  DEPTH (Real) =     0.0
  DEPTH_OFF (Real) =   0.0
  WATERTEMP (Real) =   0.0
  POINT (21.082915000000003 52.234728333333337 162.5)


Note the round brackets not <>, lower case (null) not upper case <NULL>,
equal sign with spaces around, etc.
