[Pytables-users] iterate over specific Tables

[Uwe M. <uwe...@df...>]

Hi,

I have several leaf nodes of the same table dtype:

class VideoNode(tables.IsDescription):
    ...

Not all tables in the hdf5 file are of the same type, however. How do I iterate
over all leafes which are tables of the above class, while ignoring tables with
different signatures?

i.e. I'd like to write something like:
<code>
f = tables.openFile(...)
foo = f.walkNodes('/', classname='VideoNode')
</code>
which does not work because only the class name is "Table"...

or
<code>
bar = filter(isinstance(x, VideoNode) for x in f.walkNodes('/', 'Table')))
</code>

which does not work, because x is never an instance of VideoNode.

Any ideas?

Thanks in advance
Uwe
