in reply to Should I use; Html Parser, table extract, Extractor

If what you are tryuing to do is extract the data from the table then the following code using HTML::TreeBuilder and HTML::ElementTable may be a good starting point for you:

use strict;
use warnings;
use LWP::Simple;
use HTML::TreeBuilder;
use HTML::ElementTable;

my $page = get ('http://www.ovt.ncsu.edu/cotton_soy/2004/table_11.html
+');
my $root = HTML::TreeBuilder->new_from_content ($page);
my $theTable = $root->find ('table');

die "Table not found" if ! defined $theTable;

$theTable = HTML::ElementTable->new_from_tree($theTable);

for my $row (1..$theTable->maxrow()-2)
  {
  for (0..$theTable->maxcol())
    {
    my $cellText = $theTable->cell ($row, $_)->as_text ();
    print "$cellText ";
    }

  print "\n";
  }

Note that $theTable->maxrow()-2 ignores the last two rows to avoid a problem with missing cells in those rows and the first row is skipped for the same reason.
