regexp to filter file names

17 views (last 30 days)
I have files such as the following:
s =
I only wish to process the first six files and filter out the last one which is a different format than the first six files. Note that even though some of them did not say "Default" in the file names, it is still considered default since it did not specifically mention "Potato" or other keywords.
I try not to filter it out by keywords "Potato" since there may be future files add in this cell array that contains other keywords such as "Carrot", "Bacon", etc (I don't know what they will be yet) other than "Potato". In that case, they will not be filtered out as I wish they would.
Actually I think I figure out the code after looking at your answers?
I used find(cell2mat(regexp(s,'HI_\w+_\TTTT\d_(Default)?\d+_\d+')))
Thank y'all for all the inspiration!!

What's unique about the filenames you want to keep? Do they all end in 16 like in your small sample? If so do
fileStruct = dir('*16.xlsx');
Now, just use fileStruct(k).name in your loop or wherever you need to reference the filename.

OK, though I'm still not sure what constitutes a good filename and a bad one. If it's just the presence of some list of keywords defined in advance, you might look at ismember to identify what strings, in a cell array of filenames, have any of the keywords in them.
