You may use the following program to search for multiple instances of "comp":
perl code:
  1. #! /usr/bin/perl
  2. use warnings;
  3. use strict;
  4. my ($x, @y, $val, $run, $comp);
  5. for $comp ("a", "e") {
  6.     open I, "< inputfile.txt";
  7.     for (<I>) { $x = $_ if (/^comp=$comp/ && /type=lic$/) }
  8.     close I;
  9.     @y = split /,/,$x;
  10.     $val = (split /=/,$y&#91;1])[1];
  11.     $run = (split/=/,$y&#91;2])[1];
  12.     print "$comp $val $run\n";
  13. }

Or alternatively, you may use the following perl one-liner to search for one "comp" at a time:
Code:
perl -ne '$x = $_ if (/^comp=a/ && /type=lic$/); END{@y = split /,/,$x;$v=(split /=/,$y[1])[1];$r=(split/=/,$y[2])[1];print "a $v $r\n"}' inputfile.txt
