Greetings Annie,

You can use netCDF-Java to dump out an xml representation of the metadata
in NcML. If you have the toolsUI jar (or netcdfAll), you can do the following 
to see
an example:

java -classpath toolsUI.jar ucar.nc2.NCdumpW /path/to/file -ncml

If you would like output that more closely matches that of ncdump from the
C netcdf library, simply omit the -ncml flag. If either of these looks good,
then you can use the ucar.nc2.NCdumpW class. See the NCdumpW javadoc here:

Cheers!

Sean
