Search and replace a word of text file from GUI

6 views (last 30 days)
I need to parse a text file in way like what find and replace (strrep) function does in the string. It actually has to get a word (‘new’) as input from the GUI, search within the text file for a special word (‘old’) and replace it.
Any help would be greatly appreciated

A text file is a string. So just read the file using fileread, and perform your operations on it:
str = fileread(filename);
str = strrep(str,old,new);
