使用matlab / octave将目录文件部分拆分为多个部分

Question

I would like to split pathstr into separate parts how can I do this? See example below.

PS: I'm using octave 3.8.1

dpath='tmp/h1/cli/pls/03sox_a_Fs_1000/'
[pathstr,name,ext] = fileparts(dpath)

>>>pathstr = tmp/h1/cli/pls/03sox_a_Fs_1000

If all I want is 03sox_a_Fs_1000 or pls How can I do this?

Please note the filenames will change and could be of different lengths.

Answer 1

You can use strsplit (here using Matlab) to split your string (believe it or not!) using the delimiter / :

pathstr = 'tmp/h1/cli/pls/03sox_a_Fs_1000'

[Name,~] = strsplit(pathstr,'/')

Now Name looks like this:

Name = 

    'tmp'    'h1'    'cli'    'pls'    '03sox_a_Fs_1000'

So you can select the last element using the end keyword and curly braces since the output of strsplit is a cell array:

Name = Name{end}

or end-1 to retrieve pls .

This applies to names of any length or format, as long as they are separated by / .
