Description

I cannot access meta data from meta data block within an event data block by using mdfreader.mdfinfo("filename.mf4") The mf4 file is written by our own software, but I can see all the expected meta data in the Vector mdf validator.

After debugging the mdfinfo4.py file I might have found the problem in the CommentBlock class. All the needed data is in the xml_tree variable (line 398), but it seems, that in an event data block, the meta data block does not have an "MDType" (line 404). -> CommentBlock object not filled with this data.

Additionally, I find it a little bit confusing, that all the base keys from mdfreader.mdfinfo dict have been renamed (CNBlock to CN aso.) but not the EVBlock.

Hi, I changed in dev branch: 'EVBlock' -> 'EV', indeed more consistent. added MDType = 'EV' You can check if you have what you want

Hi, I tested it with the latest dev branch and it works as expected now. Thank you!
