Body
<ul> <li>For Huge data files, I'd recommend <a href="http://search.cpan.org/perldoc?Sort%3a%3aExternal" rel="nofollow"><code>Sort::External</code></a>. </li> <li>It doesn't look like you need to parse the brackets, if the indentation does the job. Then you have to do it on "breaks", or when the indentation level 0, then you process the last record gathered, so you always look ahead one line.</li> </ul> So: <pre><code>sub to_sort_form { my $buffer = $_[0]; my ( $id ) = $buffer =~ m/(0x\p{AHex}{8})/; # grab the first candidate return "$id-:-$buffer"; $_[0] = ''; } sub to_source { my $val = shift; my ( $record ) = $val =~ m/-:-(.*)/; $record =~ s/\$--\^/\n/g; return $record; } my $sortex = Sort::External->new( mem_threshold => 1024**2 * 16 # default: 1024**2 * 8 (8 MiB) , cache_size => 100_000 # default: undef (disabled) , sortsub => sub { $Sort::External::a cmp $Sort::External::b } , working_dir => $temp_directory # default: see below ); my $id; my $buffer = <>; chomp $buffer; while ( <> ) { my ( $indent ) = m/^(\s*)\S/; unless ( length $indent ) { $sortex->feed( to_sort_form( $buffer )); } chomp; $buffer .= $_ . '$--^'; } $sortex->feed( to_sort_form( $buffer )); $sortex->finish; while ( defined( $_ = $sortex->fetch ) ) { print to_source( $_ ); } </code></pre> Assumptions: <ul> <li>The string <code>'$--^'</code> does not appear in the data on its own.</li> <li>That you're not alarmed about two 8-hex-digit strings in one record.</li> </ul>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
