The main wheels I would suggest would be
HTML::Parser or any of several others in the
HTML:: tree, and URI.
use URI;
use HTML::Parser;
my $parse = new HTML::Parser( default_h => [ sub {print shift}, 'text'
+ ],
start_h => [
sub {
my ($tag, $attr, $origtext) = @_;
if (($tag eq 'img') and ($attr->{src} =~ m#^(?:http://)?myserver\.
+#)) {
$attr->{img} = URI->new($attr->{img})->abs('http://myserver.com'
+);
print "<$tag " . join (' ', map {$_.'="' . $attr->{$_} . '"'} ke
+ys %$attr) . '>';
}
else {
print $origtext;
}
}, "tagname, attr, text"]
);
$parse->parse(join('',<>));
However this code is untested and may well need some work.
It currently would take input on STDIN and produce results
on STDOUT.

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).
