That would artificially create "record" data that you could manipulate
and combine partial segments into complete xml records to parse. Might
be faster, might not, probably would get complicated pretty quickly but
could be an option.
Without seeing actual data, it's tough to spec
stx and etx (comment lines, other data that you
don't want), then it gets a lot harder.
If you don't have at least a marginally consistent input, your only real
option is probably going to be scanning by character and looking for the
\x02 and \x03 to get a glob of data, then parse that glob
in f1:
if between [x02] and [x03]:

2. looking up by value would work, but maybe you should do it the other
direction. Your SCSI values will be unique, so use that as the key
a "simpler" logic is probably:
a) read file
b) store the LUN value from your mpath line
c) iterate over lines and find SCSI key, then
ay to break
out of your logic when the next mpath is seen.
You will also want to think about what to do with all your LUNs. You
have four per mpath, not one. Do you want to capture only one, or do
you need all of them?
