Obtaining the model topology from a Simulink model

Question

I would like to create a structure in Python which represents a Simulink model. I am aware of at least two ways of doing this - by parsing an ".mdl" file, or by using Matlab's api for communicating with the model.

Can you recommend good libraries or APIs for doing this?

In particular, I need to perform some processing on a Simulink model and I would like to do it in Python. Also I don't want to be constantly communicating with Matlab for doing this (so that I can release the floating license).

I have seen some parsers online, but they seem to be a little limited, usually not supporting components such as Bus Creators and Bus Selectors, Muxes, Demuxes, and reading UserData information.

Any help will be greatly appreciated.

Not my area, but noticed this Python parser which may be helpful.

Or you can purchase the Simulink Report Generator in order to save/manipulate the model as a XML file.

Or the *.mdl file is a readable ascii file. You could read it into a string with a fread statement, alter the string, then either save it to your format of choice or write it back out to a *.mdl file. My coworker thought of this, not me! But would require doing the editing/parsing with a routine you write yourself.
