I would first get this working without file I/O:
str = 'Add new text HERE and then the rest';
ins = strfind(str, 'HERE') + 4; % Add 4 to account for length of "HERE"
str = [str(1:ins) '(like so) ' str(ins+1:end) ];
str
You're working with XML, so make sure the new string you are creating remains valid XML.
Then, use fopen, fread, and fclose to:
- Open the original file
- Read all of its contents
- Close the original
Then do the text insertion, and then create a new file with fopen, fwrite, and fclose.

MATLAB can go either way -- I read the whole file, but fgetl can go line by line (in a "for" loop, presumably). Remember that line breaks in XML are not required (they are there for human readability), so I would hesitate to write code that demands they be there.
