Extract review comments from a model
(Author: stefan.schloesser@continental-corporation.com)
Remark: This live script uses undocumented features, by directly accessing the data structure stored in the mathworks files. This is a proof-of-concept and for teaching purpose.
Algorithm
Matlab stores the review comments of a model in an own file, named "ModelName>_comments.mldatx".
This filetype (mldatx) is (similar to .slx) a .zip file, that contains a folder structure with several files containing the data.
For the review comments, they are stored in a file with the path "fsroot/data/commentsData.dat", which again is a JSON structure.
So to extract the Review comments we will do the following:
  • Ask the user for the model name
  • Unzip the review comments file
  • Read commentsData.dat into a JSON struct
  • Sort replies behind corresponding comments by 'CommentID' and 'Key'
  • Convert JSON struct into a time table
