The following should work fine assuming there are no regular expressions, text assignments, etc. containing { or } inside the subs. With a little additional code (make a copy of the original text, remove harmful code, then search it and return sections of the original) this could be made to work for pretty much anything. Enjoy.
&get_subs('spider.pl', \@arr);
print @arr[0];
sub get_subs {
my ($start, $n, $inp, $path, $p);
$path = shift; $p = shift;
open(INP, 'spider.pl') || die;
$inp = ' ' . join('', <INP>);
close(INP);
while ($inp =~ /[\n ]sub[\n ]/g) {
$start = pos($inp) - 4;
$n = 1; pos($inp) = index($inp, '{', pos($inp)) + 1;
while ($inp =~ /(}|{)/g) {
if ($1 eq '}') { if (!(--$n)) { last; } }
else { $n++; }
}
push(@$p, substr($inp, $start, pos($inp) - $start));
}
}

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).
