I'm trying to parse input like this: 
  hostname: /                           level=incr,   1015 MB 00:00:54
+  26137 files
  hostname: /boot                       level=incr,   3731 KB 00:00:13
+      8 files
  hostname: /directory1          level=incr,   2796 MB 00:01:28     71
+ files
  hostname: /directory2                     level=incr,   1369 MB 00:5
+3:51     36 files

With this code: 
use constant
HOST_LINE => qr{
                \s+ \w+: \s [\/\w+] \s+         # host, partition
                level=\w+, \s+                  # backup level
                (\d+) \s+ (\w+) \s+             # amt backed up
                \d+:\d+:\d+  \s+                # Time
                (\d+) \s+ files                 # num. files
                }xms
              ;

my @lines = <STDIN>;

for my $line (@lines) {
    if ( $line =~ HOST_LINE ) {
        my ($files, $units, $amt_backed_up) = ($3, $2, $1);
        print "line - $line, units - $units, amt - $amt_backed_up, fil
+es $files\n";
    }
    else {
        print "here -> $line"
    }
}

and it catches the first line OK and prints the captured values. However, it's not doing that for the other lines else after that, i.e. hits the 'else' and prints "here ->...". I've checked the input file for special characters, of which there are none. In fact, I don't see anything differentiating the format of the lines, i.e. don't know why only the first line is parsed correctly.

Thoughts, anyone?
