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.

NAME
mkdir -- make directories SYNOPSIS
mkdir [-pv] [-m mode] directory_name ... DESCRIPTION
The mkdir utility creates the directories named as operands, in the order specified, using mode rwxrwxrwx (0777) as modified by the current umask(2). The options are as follows: -m mode Set the file permission bits of the final created directory to the specified mode. The mode argument can be in any of the formats specified to the chmod(1) command. If a symbolic mode is specified, the operation characters ``+'' and ``-'' are interpreted rela- tive to an initial mode of ``a=rwx''. -p Create intermediate directories as required. If this option is not specified, the full path prefix of each operand must already exist. On the other hand, with this option specified, no error will be reported if a directory given as an operand already exists. Intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permission for the owner. -v Be verbose when creating directories, listing them as they are created. The user must have write permission in the parent directory. DIAGNOSTICS
The mkdir utility exits 0 on success, and >0 if an error occurs. SEE ALSO
rmdir(1) COMPATIBILITY
The -v option is non-standard and its use in scripts is not recommended. STANDARDS
The mkdir utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. HISTORY
A mkdir command appeared in Version 1 AT&T UNIX. BSD
January 25, 1994 BSD
