Well, not knowing your system nor shell (which you did not mention), based on your examples and requirements, and hoping I understood and interpreted everything correctly, I've come up with this, which works on linux and bash:
Code:
#!/bin/bash
# set -vx
function grepit () {
                  eval $DIRS" | cut -d\" \" -f1 > pattfile"
                  grep -f pattfile $fn >$fn.grep
                 }

FIRST=1
DIRS="cat "
while read line
     do if [ "${line:0:3}" != "dir" ]
            then    [ "$FIRST" -eq "0" ] && grepit
                    fn=$line
                    FIRST=0
                    DIRS="cat "
            else    DIRS=$DIRS" "$line"/log*.txt"
       fi
     done <xyz.txt
grepit
rm pattfile

Results will finish up in respective "filename.grep". Pls. test and come back with results.

gen_keymap

GEN_KEYMAP(1)						  Ubuntu General Commands Manual					     GEN_KEYMAP(1)

NAME

     gen_keymap -- generate a keyboard map decision tree

SYNOPSIS

     gen_keymap list ...

DESCRIPTION

     gen_keymap generates a decision tree from a set of keyboard maps which can be used to help a user decide which keyboard map to use.  The pro-
     gram using the decision tree typically asks the user to press some keys; at each step, it examines the returned keycode and uses it to prune
     the list of possible keyboard maps until there is only one left.

OPTIONS

     --version
	   Show program's version number and exit.

     -?, --help
	   Show help text.

     -v, --verbose
	   Be more verbose.

     -mMINLEN, --minlen=MINLEN
	   Too-short keymaps are skipped (default: 30 entries).

     -g, --graph
	   Generate a hopefully-nice-looking .dot file.

     --maps
	   Print the to-be-processed keymaps

     -i, --installer
	   Input files are in d-i map form.

     -IDIRS, --inc=DIRS, --include=DIRS
	   Add a directory to the search path.

     -oFILENAME, --output=FILENAME
	   Set output file (default: stdout).

     -fFILTER, --filter=FILTER
	   Include only the branches leading to these keymaps.

     -uUSEONLY, --useonly=USEONLY
	   Start generating the tree based only on these keymaps.  (The difference between --filter and --useonly is that the former generates the
	   whole tree and then prunes it, while the latter only generates a reduced tree to begin with.  This may have implications for perfor-
	   mance on large trees.)

     -sSKIP, --skip=SKIP
	   Keymaps to skip.

     -t, --test
	   Test the generated maps.

     --interactive
	   Ask user to choose among indistinguishable keymaps.
