Does anybody know a way to access the Text of a Simulink DocBlock in a model via command line, using find_system command ?

% Find docblocks in model
dBlkH = find_system('MyModel', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock');
% Extract the docblock text
dBlkUData = get_param(dBlkH(1), 'UserData');
bBlkText = dBlkUData.content;

Thanks Tabrez, this is helpful ! :-)
If I add a 'FindAll', 'on' it is returning me the Handles to the DocBlocks (otherwise a cell array). I can use either of it.
>> dBlkH = find_system('tl_vwe_model', 'FindAll', 'on', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock')
dBlkH =
5.0002
8.0002
>> dBlkH = find_system('tl_vwe_model', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock')
dBlkH =
2×1 cell array
'tl_vwe_model/ChangeHistory'
'tl_vwe_model/Requirements'
I still do not know why this only finds the blocks on top model level (not in the lower subsystem levels).

Above search command should find the DocBlock in all level of model.
Try to use the 'SearchDepth' option and check there is any difference.

尝试引用非结构体数组的字段。
出错 Untitled5 (line 31)
bBlkText = dBlkUData.content;
