You explained your problem quite inconsistently, so a few questions first:

I take it your files are of the form

Code:
key,value

where "key" is something like "DB1|TB1|" and "value" is everything after that. You search for every of these keys, compare the differences in the corresponding "value"s and record these differences, yes?

If so: can there be more than one line for each key in each file? i.e.

file1
Code:
DB1|TB1|C1,C2

file2
Code:
DB1|TB1|C1
DB1|TB1|C2

and would this result in "no difference" or in something else?

Then, are the entries in "value" all separated by commas and can that be used consistently as a delimiter?

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
