Mojo::DOM makes such things fairly trivial. Consider the following:
#!/usr/bin/perl
use strict;
use warnings;
use feature 'say';
use Mojo::DOM;
my $html = '<h2>2.1. Match Literal Text</h2>
<h2>2.2. Match Nonprintable Characters</h2>
<h2>2.3. Match One of Many Characters</h2>';
my $dom = Mojo::DOM->new( $html );
#for each hr
foreach my $hr ( $dom->find('h2')->each ){
# grab the text
my $class = $hr->text;
# remove x.x.
$class =~ s/\-?\d+\.\d+\. //g;
# update the DOM
$hr->attr('class' => $class );
}
# display updated DOM
say $dom;
Prints:
<h2 class="Match Literal Text">2.1. Match Literal Text</h2>
<h2 class="Match Nonprintable Characters">2.2. Match Nonprintable Char
+acters</h2>
<h2 class="Match One of Many Characters">2.3. Match One of Many Charac
+ters</h2>

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).
