Re: [Laurent_R] last occurance

So you just need the numbers from the last occurence of PM? Or the whole PM .. .xml line?
I have to find last PM(/d+)*.xml in a file
Seeing how you said find last occurrence in a file, I'm assuming these are lines in a file. So therefore here are a few examples, not clear exactly if you are just wanting the digits from the last occurrence or the whole line.
__DATA__
ggdt 2365 237 PM23jhfy&%_kkf.xml wknw f
wef ^& 8* uy y w9 8y
ivhodio wroio wroi icvo PM12_uryt&^%_uieg.xml uet.
If you want last occurrence of digits, you could do this.
open my $fh, '<', 'file.txt' or die "failed: $!";
my ($str) = map { $_ =~ /.*(?:PM)(\d+)/ } reverse <$fh>;
close $fh;
print $str;
__OUTPUT__
12
If you want the whole line including .xml you could do this.
open my $fh, '<', 'file.txt' or die "failed: $!";
my ($str) = map { $_ =~ /.*(PM.*\.xml)/; } reverse <$fh>;
close $fh;
print $str;
__OUTPUT__
PM12_uryt&^%_uieg.xml
