Hi to everybody!

I found a strange addXML (1.7) behavour: it doesn't always detect all 
variables. As an example it follows the ncdump -h of a netcdf file and the 
corresponding xml produced by addXML.  The netcdf file (5MB)  is avaliable at 
ftp://giotto.casaccia.enea.it/emanuele.lombardi/giovanna.nc

As you can see the netcdf variables V, U, TEMP, S, SIGMA, W and ITT are not 
present in the xml file, but this is wrong!

I don't see any reason for that and I can only suppose the problem arises from 
the existance in the netcdf file of two orizontal axes (nxt and nxu) and two 
vertical axes (nyt and nyu). Is it possible there is a bug in addXML ?

Unfortunately I'm not able to program in java so I can't try to solve the 
problem on my own. Can you help me, please?

Thank you very much for any help,
ciao from Italy,

Emanuele
