Maybe you need something like this:
#!/usr/bin/perl
use strict;
use warnings;
local $/ = "\nGenerating";
while(my $entry = <DATA>){
my ($table,$count) = $entry =~ /Summary of ([^\s]+).*(\d+)/s;
print $table,": ",$count,"\n" if $count > 1;
}
__DATA__
Generating Summary of table_1
(count(*))
1
Generating Summary of table_2
(count(*))
2
