Here's my go with HTML::TreeBuilder.

The docs discuss inline editing under the $h->contents_refs_list

You may have to adjust depending on how "unpredictable" the HTML is. 

#!/usr/local/bin/perl

use strict;
use warnings;

use HTML::TreeBuilder;
  
my $root = HTML::TreeBuilder->new_from_file(*DATA)
  or die qq{cant build tree\n}; 

my $noclass = $root->look_down(
  _tag  => q{div}, 
  class => q{noclass},
);
die qq{noclass not found\n} unless $noclass;

my $replaced;
for my $item_r ($noclass->content_refs_list) {
  next if ref ${$item_r};
  ${$item_r} = lookup_replacement(${$item_r});
  $replaced++;
}
die qq{no replace\n} unless $replaced;

my $html = $root->as_HTML(undef, qq{  }, {});

print qq{$html\n};

sub lookup_replacement{
  my $lookup = shift;
  # find replacement
  return q{something};
}

__DATA__
<html>
<head>
  <title>tb_test</title>
</head>
<body>
  <div align="center" class="noclass">nothing</div>
</body>
</html>
