Re: Parsing record into hash

Your question isn't very clear but let's see what do you think about this:

open my $fd, '<', 'foo' or die open "$!\n";
my ($h, @arr);
## assuming <eor> and <eoh> are always at the end of their lines
while (<$fd>) {
  $h .= $_;          ## We store header in $h. I won't parse it.
  last if /<eoh>$/;
}
my $c = 0;
while (<$fd>) {
  next if /^\n$/;
  my @fields = split / /, $_;
  foreach (@fields) {
    my ($k, $v) = $_ =~ /^(<[^>]+>)(.*)$/;
    next if $k eq '<eor>';
    $arr[$c]{$k} = $v;
  }
  $c++ if /<eor>$/;
}
close $fd;

Output of use Data::Dumper;print Dumper \@arr;

Update: Removed an intermediate step and did some other minor tweaks. Now it's smaller and probably faster.

Wow, Thank you, this what I am looking for the info between the <> is the key and the data follows. You make it look simple. Now I have to read through the code to really understand what just happened. Thanks Mike	[reply]
