benoit michau michau.benoit at gmail.comHi, I have been using the scripts here: https://github.com/ANSSI-FR/pycrate/tree/master/pycrate_csn1dir/generator/ - extract.py: to extract csn.1 definitions from those 3GPP 44.018, 44.060 and 24.008 after converting them to txt files with microsoft word. I am not sure it would work well with ETSI specs in PDF converted to text. - gen.py: to convert csn.1 specs to Python files by batch. Beware some pathes are hardcoded, this may have to be adjusted in the header of those scripts.
