Parse text from a .txt file and save multiple output .txt

[rattlerskin]

I would prefer to use the chapter titles in my table of contents, since they are shorter and have already been cleaned up in my earlier code. That's the issue I've been having- trying to figure out how to pull the chapter titles out from my earlier lines and use them within the file name. I would also prefer not to need line 13, since it is relying on a certain number of spaces after the chapter title as opposed to simply pulling out the text I have already separated and pulling the text out of the associated line number. Any ideas?
