I've a file to parse.

Here's a sample of its contents (this is cat -vue's output, and there are many more "sections" like the ones below in that file. about 12,000 sections like the ones below. I masked IPs, so if you see "x.x.x.x" there used to be an IP there :) ):

The task at hand is as follows: I need to come up with a multiline regex that matches everything between "abc1-wl-wlc2.domain.com" and "apl02-wl-wlc1.domain.com", so I can process the contents of that file, section by section. if it helps any, I'm mainly interested in getting a list of hostnames that have a "Failed Binary transfers: 1" in their section..

Any thoughts / suggestions on the multiline?

I tried doing it on my own, but unfortunatelly without much success.. I know about the "m" modifier on the end of my regex, btw. I'm not completely useless, but I can't seem to craft the necessary regex for this task :/
