MATLAB: Replacing certain text from a .txt file.

regular expression

How can the following expressions be replaced? For example expressions of the form:
     FirstText [Text1@/ Text2@/ Text3] LastText
is to be preplaced by
     FirstText Text1 LastText; FirstText Text2 LastText; FirstText Text3 LastText

Best Answer

If it is all you have to do, here is an example:
 str = 'FirstText [Text1@/ Text2@/ Text3] LastText' ;
 tokens = regexp( str, '(.*)[([^@]+)@/ ([^@]+)@/ ([^\]]+)\] (.*)', 'tokens', 'once' ) ;
 outStr = sprintf( '%s %s %s; %s %s %s; %s %s %s', tokens{[1,2,5,1,3,5,1,4,5]} ) ;
which outputs
 outStr = FirstText  Text1  LastText; FirstText  Text2  LastText; FirstText  Text3 LastText
Note that you don't need regular expressions for this:
 tokens = strsplit( str, {' [', '@/ ', '] '} )
 tokens =
  1×5 cell array
    'FirstText'    'Text1'    'Text2'    'Text3'    'LastText'
But what is the context? I suspect that you have to apply this to a more complex case. Could you give a real slice of what you have to process?
