Have a look at $h->splice_content(...).

The cut down example below inserts new text immediately after the opening div tag (if a text element is not found).

#!/usr/local/bin/perl

use strict;
use warnings;
use HTML::TreeBuilder;

my $html = do{local $/;<DATA>};
my $replace = q{replaced};
my $edited = edit($html, $replace);
print $edited;

sub edit{
  my $html = shift;
  my $replace = shift;
  
# my $root = HTML::TreeBuilder->new_from_file($html_file)
#   or die qq{cant build tree\n}; 

  my $root = HTML::TreeBuilder->new_from_content($html)
    or die qq{cant build tree\n}; 

  my $class3 = $root->look_down(
    _tag  => q{div}, 
    class => q{class3},
  );
  die qq{class3 not found\n} unless $class3;

  my $rep_class3;
  for my $item_r ($class3->content_refs_list) {

      next if ref ${$item_r};
      ${$item_r} = $replace;
      $rep_class3++;

  }
  if (not $rep_class3){
    $class3->splice_content(1, 0, $replace);
  }
  #die qq{Class3 not replaced\n} unless $rep_class3;

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

__DATA__
<div align="center" class="class1">something</div>
<div align="center" class="class2">something else</div>

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.
