As contributed by merlyn, reusing the available CPAN module is probably the best way to go. However, if you just want to see how it's done and presuming that you would like to see all links then here is how Troc does it with his collate module. This doesn't handle links in Javascript but that's a difficult problem as links in Javascript can be the value of expressions. 
    open(DOC, "<$doc_filename") || die "can't open doc $doc_filename: 
+$!";
    binmode(DOC);
    $document = <DOC>;
    close(DOC);

    while ($document =~ m{< ?(.*?) ?>}g) {
      $tag = $1;
                                        # find tags with links
      $link =
        ($tag =~ m{
                    (background|src|usemap|action|href)\s?=\s?
                    (['"]*)
                    ([^\2 ]+)\2
                 }xi)[2];
      next unless (defined $link);

in thread How can I find the links in HTML tags? by Anonymous Monk

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
