Thank you for the feedback.

Shifting gears to your latest and I have to ask, where did that particular file come from?

Thinking about the problem at hand with that file, is the format for each section (1 per DN) reliable insofar as position on the line for each "line type"? If so, this could be incredibly easy to solve because that would make it a simple substring/screen scraping problem. I'd just read a whole block as a single string (including the Cr/Lf combinations and map it out for substring extraction.

Also (and asking because the file you attached is obviously a snippet of a larger file), does that last section end with the constant string of dashes as the other sections do?
