When I fix the syntax errors (and write $string instead of string - always Use strict and warnings!), your second piece of code works for me, as in it prints "match". But you should not be Parsing HTML/XML with Regular Expressions! For one, the order of items in an HTML class attribute can change. Use something like Mojo::DOM, which supports selectors, instead.

use warnings;
use strict;
use Mojo::DOM;

my $html = <<'END_HTML';
<span class="Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)" data-reactid="
+33">a</span>
<span class="D(ix) Mb(-4px) Fz(36px) Fw(b) Trsdu(0.3s)" data-reactid="
+34">b</span>
<span class="Mb(-4px) Fz(36px) D(ib) Fw(b) Trsdu(0.3s)" data-reactid="
+35">c</span>
END_HTML

my $dom = Mojo::DOM->new($html);
my $spans = $dom->find('span[class~="D(ib)"]')->each(
    sub { print "==> $_ <==\n" } );

__END__

==> <span class="Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)" data-react
+id="33">a</span> <==
==> <span class="Mb(-4px) Fz(36px) D(ib) Fw(b) Trsdu(0.3s)" data-react
+id="35">c</span> <==
