HTML::Seamstress::new_from_file() now reblesses the whole tree
To date, Seamstress has supported tree-based rewriting of HTML trees by blessing the $tree into a class which has these superclasses - HTML::Seamstress, HTML::Element::Library, HTML::Element, and any local Element library. That way, you can rewrite the $tree by going:

$tree->this;
$tree->that;

Well, that was all good and fine until today when I tried to call this and that on a subtree of $tree:

my $div = $tree->look_down('_tag' => 'div');
$div->this;
$div->that;

and it did not work because $div was blessed into HTML::Element instead of a class which inherited from the above-mentioned superclasses.

So, the solution was to simply bless all nodes of $tree into the same class. A test case 02.treebless.t shows the new functionality:


package tree::bless;

use Test::More qw(no_plan);
use TestUtils;

use base qw(HTML::Seamstress) ;

my $root = 't/html/treebless';

my $tree = __PACKAGE__->new_from_file("$root.html");

my $li = $tree->look_down(class => 'greg');

is (ref $li, 'tree::bless', 'blessed into proper class');
