If you don't mind storing your data in a hash, it doesn't have to be adaptive. Instead you can parse the line pairs as hash keys & values respectively. Something like this:

$ cat t.pl #!/usr/bin/perl use strict; use warnings; use Data::Dumper; my %CELLS; my $tmp; my $curCELL; my $curCELLR; while (<DATA>) { # skip blank lines next if /^\s*$/; # Line isn't empty, so current line is a list of field names # and the next line is a list of the values my @names = split /\s+/, $_; my @values = split /\s+/, <DATA>; $curCELL = $values[0] if $names[0] eq 'CELL'; $curCELLR = $values[0] if $names[0] eq 'CELLR'; # Store the name/value pairs (if we have both keys) next unless defined $curCELL and defined $curCELLR; @{$CELLS{$curCELL}{$curCELLR}}{@names} = @values; } print Dumper(\%CELLS); __DATA__ NEIGHBOUR RELATION DATA CELL LUC325C CELLR DIR CAND CS LUC325B MUTUAL BOTH NO KHYST KOFFSETP KOFFSETN LHYST LOFFSETP LOFFSETN 3 0 3 0 TRHYST TROFFSETP TROFFSETN AWOFFSET BQOFFSET 2 0 5 3 HIHYST LOHYST OFFSETP OFFSETN BQOFFSETAFR 5 3 0 3 CELLR DIR CAND CS LUC116A MUTUAL BOTH NO KHYST KOFFSETP KOFFSETN LHYST LOFFSETP LOFFSETN 3 0 3 0 TRHYST TROFFSETP TROFFSETN AWOFFSET BQOFFSET 2 0 5 3 HIHYST LOHYST OFFSETP OFFSETN BQOFFSETAFR 5 3 0 3 CELLR DIR CAND CS LUC204A MUTUAL BOTH NO KHYST KOFFSETP KOFFSETN LHYST LOFFSETP LOFFSETN 3 0 3 0 TRHYST TROFFSETP TROFFSETN AWOFFSET BQOFFSET 2 0 5 3 HIHYST LOHYST OFFSETP OFFSETN BQOFFSETAFR 5 3 0 3 CELL LUC082B

When I run it, I get the following:

$ perl t.pl $VAR1 = { 'LUC325C' => { 'LUC204A' => { 'KHYST' => '', 'OFFSETN' => '0', 'TROFFSETN' => '0', 'OFFSETP' => '3', 'LOFFSETN' => undef, 'DIR' => 'MUTUAL', 'LOHYST' => '5', 'LHYST' => '3', 'CAND' => 'BOTH', 'BQOFFSET' => '3', 'LOFFSETP' => '0', 'CELLR' => 'LUC204A', 'KOFFSETN' => '0', 'KOFFSETP' => '3', 'TRHYST' => '', 'HIHYST' => '', 'CS' => 'NO', 'AWOFFSET' => '5', 'BQOFFSETAFR' => '3', 'TROFFSETP' => '2' }, 'LUC116A' => { 'KHYST' => '', 'OFFSETN' => '0', 'TROFFSETN' => '0', 'OFFSETP' => '3', 'LOFFSETN' => undef, 'DIR' => 'MUTUAL', 'LOHYST' => '5', 'LHYST' => '3', 'CAND' => 'BOTH', 'BQOFFSET' => '3', 'LOFFSETP' => '0', 'CELLR' => 'LUC116A', 'KOFFSETN' => '0', 'KOFFSETP' => '3', 'TRHYST' => '', 'HIHYST' => '', 'CS' => 'NO', 'AWOFFSET' => '5', 'BQOFFSETAFR' => '3', 'TROFFSETP' => '2' }, 'LUC325B' => { 'KHYST' => '', 'OFFSETN' => '0', 'TROFFSETN' => '0', 'OFFSETP' => '3', 'LOFFSETN' => undef, 'DIR' => 'MUTUAL', 'LOHYST' => '5', 'LHYST' => '3', 'CAND' => 'BOTH', 'BQOFFSET' => '3', 'LOFFSETP' => '0', 'CELLR' => 'LUC325B', 'KOFFSETN' => '0', 'KOFFSETP' => '3', 'TRHYST' => '', 'HIHYST' => '', 'CS' => 'NO', 'AWOFFSET' => '5', 'BQOFFSETAFR' => '3', 'TROFFSETP' => '2' } }, 'LUC082B' => { 'LUC204A' => { 'CELL' => 'LUC082B' } } }; $
