..tried to use HTML::Parser, but it was ended up pretty ugly,

What didn't you like with using HTML::Parser ?

#!/usr/bin/perl
use warnings;
use strict;
use HTML::Parser;

my %inside = ();
my $tbl = -1; my $col; my $row;
my @table = ();

my $p = HTML::Parser->new(
  handlers => {
    start => [ \&start,'tagname' ],
    end   => [ \&end,  'tagname' ],
    text  => [ \&text, 'text' ],      
  }
);
$p->parse_file(\*DATA); # or filename

# output
for my $t (0..$#table){
  print "\nTable $t\n";
  for my $r (0..$#{$table[$t]}){
    my $line = join "\t",$r,@{$table[$t][$r]};
    print "$line\n";
  }
}


sub start {
  my $tag  = shift;
  $inside{$tag} = 1; 
  
  if ($tag eq 'table'){
    ++$tbl; $row = -1;
  } elsif ($tag eq 'tr'){
    ++$row; $col = -1;
  } elsif ($tag eq 'th'){
    ++$col;
    $table[$tbl][$row][$col] = ''; # or undef
  }
} 

sub end {
  my $tag = shift;
  $inside{$tag} = 0;
}

sub text {
  my $str = shift;
  if ( $inside{'th'} ){
    $table[$tbl][$row][$col] = $str;
  }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
