You mean something similar to:
results = []
for table in h5file.walkNodes("/", "Table"):
results.append([row['col'] for row in table.where('ID=%d' % your_ID)
? (this for all tables in a file; generalizing to multiple files is
left as an exercise to the reader ;-)
Tell us if this is not what you are after.
