Compound datatypes with h5py: datatype inside an attribute

I'm using Silo with HDF5, and I'm having trouble accessing some of the metadata with h5py. It spits out some rather unusual HDF5 structuring, where it puts a DATATYPE inside a DATATYPE. Here's an excerpt of the output from h5dump:

DATATYPE "sigma_t" H5T_STD_I32LE;
   ATTRIBUTE "silo" {
      DATATYPE  H5T_COMPOUND {
         H5T_STRING {
            STRSIZE 5;
            STRPAD H5T_STR_NULLTERM;
            CSET H5T_CSET_ASCII;
            CTYPE H5T_C_S1;
         } "meshid";
         H5T_STRING {
            STRSIZE 15;
            STRPAD H5T_STR_NULLTERM;
            CSET H5T_CSET_ASCII;
            CTYPE H5T_C_S1;
         } "value0";
         H5T_STD_I32LE "ndims";
         H5T_STD_I32LE "nvals";
         H5T_STD_I32LE "nels";
         H5T_IEEE_F32LE "time";
         H5T_STD_I32LE "use_specmf";
         H5T_STD_I32LE "centering";
         H5T_ARRAY { [3] H5T_STD_I32LE } "dims";
         H5T_ARRAY { [3] H5T_STD_I32LE } "zones";
         H5T_ARRAY { [3] H5T_STD_I32LE } "min_index";
         H5T_ARRAY { [3] H5T_STD_I32LE } "max_index";
         H5T_ARRAY { [3] H5T_IEEE_F32LE } "align";
      }
      DATASPACE  SCALAR
      DATA {
      (0): {
            "mesh",
            "/.silo/#000004",
            2,
            1,
            100,
            0,
            -1000,
            111,
            [ 10, 10, 0 ],
            [ 9, 9, 0 ],
            [ 0, 0, 0 ],
            [ 9, 9, 0 ],
            [ 0.5, 0.5, 0 ]
         }
      }
   }
   ATTRIBUTE "silo_type" {
      DATATYPE  H5T_STD_I32LE
      DATASPACE  SCALAR
      DATA {
      (0): 501
      }
   }

Basically, f['sigma_t'].attrs['silo'] returns a tuple with all of the correctly formatted data but without any of the associated labels for the data types. (I need to know the names meshid, value0, etc.) Is there a way to get this? I'm at a loss.

Example file and script

HDF5 file contains the "sigma_t" field, and the actual data is stored in /.silo/#000004.

Script:

import h5py
f = h5py.File('xsn.silo', 'r')
print f['sigma_t'].attrs['silo']

Result:

('mesh', '/.silo/#000004', 2, 1, 100, 0.0, -1000, 111, array([10, 10,  0], dtype=int32), array([9, 9, 0], dtype=int32), array([0, 0, 0], dtype=int32), array([9, 9, 0], dtype=int32), array([ 0.5,  0.5,  0. ], dtype=float32))

What I also want is something like:

('meshid','value0','ndims', ..., 'align')

Is this possible?

I got an answer from the developer via the h5py Google groups page: it's a bug that will be fixed in h5py 1.4.

What I ended up doing is:

import h5py
f = h5py.File('xsn.silo', 'r')
group = f['sigma_t']
attr_id = h5py.h5a.open(group.id, 'silo')
data = dict(zip(attr_id.dtype.names, group.attrs['silo'],))
