Simple little module that allows you to access the text inside nested tables using a multidimensional array. The html can either be in a variable or from a file.

usage:
my $table = Table->parse_it(\$content); or
my $table = Table->parse_it($filename);

then:
print $table->[$table][$row][$col]; 

package Table;

use strict;
use HTML::Parser;

## PRIVATE
my $table = [];
my $tb_count;
my $tb_idx;
my $row;
my $column;
my $table_status;         

my @save;


sub new {
  my $type = shift;
  return bless $table, $type;
}

sub parse_it {
  my $self = shift;
  my $src  = shift;

  my $p    = HTML::Parser->new( api_version  => 3,
                handlers     => [  start => [ \&_start, "tagname"],
                           end   => [ \&_end,   "tagname"],
                           text  => [ \&_text,  "dtext"],
                        ],
                marked_sections => 1,
                  );

  if (ref($src)){
    $p->parse($$src) or return;
  }else{
    $p->parse_file($src) or return;
  }
  return 1;
}

sub _start {
  my $tag = shift;
  if ($tag eq 'table'){
    push @save, [$tb_idx, $row, $column];
    $row = $column = 0;
    ++$tb_count;
    $tb_idx = $tb_count;
    ++$table_status;
  }
  $row++     if ($tag eq 'tr');
  $column++  if ($tag eq 'td');
}

sub _end {
  my $tag = shift;
  if ($tag eq 'table') {
    ($tb_idx, $row, $column) = @{ pop @save };
    --$table_status;
  }
  $column = 0 if ($tag eq 'tr');
}

sub _text {
  my $text = shift;
  $text =~ s/\xa0//;
  $table->[$tb_idx][$row][$column] .= $text if ($table_status) &&
                                               ($text !~ m/^\s+$/) &&
                               ($text);
}

return 1;
