If you had given the names of those two files (in that order) as the names of the files on the last line of the script I provided, the output would have been the output you requested! I.e., the names of the files in 1st input file (after discarding the directories in which those files were located) that were not found in the 2nd input file (after discarding the directories in which those files were located). So, what are you now trying to do with grep -v -f that wasn't already done by the code I provided???
Your script worked flawlessly. I was able to get the difference in 1 shot.

Thanks

for i in bat*.tar.gz 
do
tar tf $i | grep ".xml" >> batch-file-list
done

echo "get missing list"
grep -v -f batch-file-list all-xml-file-list

Note that in tar files i look only for xml files, you might need to modify a bit.
Thanks for your help. I had to use Don's script as it handled the stripping of directory component in files names

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
