Aspen Plus variables access through Active X

I am trying to access stream results of Aspen Plus simulation through active x but can't access the fields within the results tables although the variables call is available on the 'variable explorer'. My access method is:
Aspen.Tree.FindNode("\Data\Results Summary\Stream-Sum\Stream-Sum\Table")
i get an interface object which contains a 'elements' field which is also an interface object. However, the findnode function doesn't work on that COM object.
I found a python code on "kitchingroup" under aspen tag that shows how to access all the variables:
import os
import win32com.client as win32
aspen = win32.Dispatch('Apwn.Document')
aspen.InitFromArchive2(os.path.abspath('data\Flash_Example.bkp'))
def print_elements(obj, level=0):
if hasattr(obj, 'Elements'):
print ' '*level + obj.Name
for o in obj.Elements:
print_elements(o, level + 1)
else:
print ' '*level, obj.Name, ' = ', obj.Value
print_elements(aspen.Tree)
aspen.Close
can somebody provide a MATLAB equivalent for this code? the AI translated code didn't work.

Hi Muhammed,
To access the stream results of an Aspen Plus simulation using ActiveX in MATLAB, you'll need to use COM automation like the Python script you provided.
There is a file exchange that helps to outline the Aspen Plus and Matlab connection through COM Technology. Leverage the following file exchange from below:
I believe that the MATLAB file provided in the file exchange has the python equivalent of your code.
Hope this helps!
