Organizing text file contents

I wanted to know which method would be best to organize the contents of a text file in matlab. My goal is to import an MS file which has its contents organized by headings. I want it to detect the type of heading set and choose that portion under that heading only. Thanks. God bless.

@Nathnael Bekele: what exactly is an "MS file"? Please show us on this list of supported filetypes:

I meant an MS word file.
