Thanks so much Scrutinizer. It looked like it was printing out some manner of counter (possibly string length?) as the first field of every line. I adjusted your code slightly and also for simplicity sake took out the leading space in the input file. I also needed to transcribe your code to a one-liner as I was passing output into it via pipe (I presented it as a file above for simplicity sake).
Thus, your code transcribed awk -F '[][]' '{for(i=2; i<=NF; i+=2) if($i~/<Ob>/){split($i,F," "); print i,$1 F[1]; next}}'gave me this:
I adjusted to awk -F '[][]' '{for(i=2; i<=NF; i+=2) if($i~/<Ob>/){split($i,F," "); print $1 F[1]; next}}' and while I haven't investigated in detail, that seems to have done the trick. Thanks so much!

Unfortunately no Don, the string with <Ob> can appear anywhere in the line. Nevertheless, I did a bit of an adjustment to Scrutinizer's code and it seems to be working very well. Thank you so much Don.
I'm at wits end with this issue and my troubleshooting leads me to believe it is a problem with the file formatting of the array referenced by my script:

dpkg-awk
DPKG-AWK(1) General Commands Manual DPKG-AWK(1)NAME
dpkg-awk - Utility to read a dpkg style db file
SYNOPSIS
dpkg-awk [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> ..
DESCRIPTION
dpkg-awk Parses a dpkg status file (or other similarly formatted file) and outputs the resulting records. It can use regex on the field
values to limit the returned records, it can also be told which fields to output, and it can sort the matched fields.
OPTIONS -f filename
--file filename
The file to parse. The default is /var/lib/dpkg/status.
-d [#]
--debug [#]
Each time this is specified, it increased the debug level.
-s field(s)
--sort field(s)
A space or comma separated list of fields to sort on.
-n field(s)
--numeric field(s)
A space or comma separated list of fields that should be interpreted as numeric in value.
-rs ??
--rec_sep ??
Output this string at the end of each output paragraph.
-h
--help Display some help.
fieldname
The fields from the file, that are matched with the regex given. The fieldnames are case insensitive.
out_fieldname
The fields from the file, that are output for each record. If the first field listed begins with ^, then the list of fields that
follows will NOT be output.
BUGS
Be warned that the author has only a shallow understanding of the dpkg packaging system, so there are probably tons of bugs in this pro-
gram.
This program comes with no warranties. If running this program causes fire and brimstone to rain down upon the earth, you will be on your
own.
This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg.
