You can also achieve your purpose with a nested grep.
#!/usr/bin/perl -w
use strict;
my @texts = ('this is 110',
'cats have 9 lives',
'dogs have 4 legs',
'no numbers here',
'my uncle has 5 children and 17 grandchildren');
my @numbers = (1, 11, 5, 4, 67, 9, 45);
# for efficiency, we turn all numbers into RegExes
my @regex_num = map {qr /\D$_\D/} @numbers;
my @matches =
grep {my $txt=$_; grep {$txt =~ /$_/} @regex_num
} @texts;
print join "\n", @matches, "\n";
__END__
cats have 9 lives
dogs have 4 legs
my uncle has 5 children and 17 grandchildren
Your request is a special case of another interesting one that was answered some weeks ago (
comparing arrays). Please have a look at it also for a discussion on efficiency.
