    Hi karana, I have tried using CAM::PDF module. I think it helps you.

    use strict;
use warnings;
use CAM::PDF;
use CAM::PDF::PageText;

my $file = $ARGV[0];
my $search = $ARGV[1];

my $doc = CAM::PDF->new($file) || die "$CAM::PDF::errstr\n";
my $pages = $doc->numPages();

for my $pg (1..$pages)
{
   my $foo = $doc->getPageText($pg);
   my ($data) = $foo =~ m/$search\s*(\d+)/si;
   print "In $pg page: $search Value is $data\n";
}
__END__
Output is:
In 1 page: def Value is 20

      I must add another vote for CAM::PDF. My problem was parsing orders which arrived in pbd, and this module (with few lines of code just like above example) made that hard task easy.

      I did examine all other PDF modules on CPAN, and concluded that there is some great code if you want to remix PDFs, but for extracting content, CAM::PDF is clear winner for me.
