Replacing text using an external text file

[amitzinman]

So, I've been tasked with coming up with a solution to this:
We are building an automated system for creating a short reel with some text.
replacing the images is simple, but I need to find an easy way of replacing the text.
I've checked the text replace script but it doesn't really do what I need.
I have let's say five comps, 001-005 with text layers inside.
I need to replace the text values in these text layers by using an external text file.
would that be difficult to do?

The problem with using this script as I see it is that it doesn't update an existing project. Rather, it creates new comps with updated information.
I have one project that I need to update with external information. Creating new comps will just mess it up
