Assuming you want output only if there is a matching chapter and figure number:
use strict;
use warnings;
# avoid using $a and $b
my $f='figure1 vdfsvh figure3 vdsvjjh';
my $ch='chapter 3 svbjjvfh chapter5';
my @figs = $f =~ /figure\s*(\d+)/g;
my %chaps;
$chaps{$_}++ for ( $ch =~ /chapter\s*(\d+)/g );
for my $i (@figs) {
print "href=\"chapter $i.html#figure $i\">figure $i\n" if exis
+ts $chaps{$i};
}

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).

or How to display code and escape characters
