title: How to get a text file read line by line?
body: <p>I am creating an application which is text file reader but It reads the text file content line by line and then if a reserved word is red a function will execute.
  For example I have a text file that contains the reserve word [PlaySound]+ sound file on its first line, when the reader reads the line a function will execute and plays the music file that is with the reserve word. </p>
  
  <p>So is it possible to create this? and if it is how can i make the line reader?</p>
