in reply to Any Alternative to HTML::TreeBuilder::XPath?

What is your expected output? Perhaps you just need to implement a workaround:

use warnings;
use strict;
use HTML::TreeBuilder::XPath;
use Data::Dump;

my $tree= HTML::TreeBuilder::XPath->new;
$tree->parse(<<'ENDHTML');
<html><body><table>
<tr> <td>Foo</td> <td>Ba<em>r</em>     </td> </tr>
<tr> <td>Quz</td> <td><b>Ba<i>z</i></b></td> </tr>
</table></body></html>
ENDHTML
$tree->eof;

dd map {$_->as_text} $tree->findnodes('/html/body//td');

dd $tree->findnodes_as_strings('/html/body//td');

__END__

("Foo", "Bar", "Quz", "Baz")
("Foo", "Bar", "Quz", "Baz")
