regex - extract data from web page

Hi,
My html looks like this

<meta name="description" content="New info! Code: http://www.example/index.html Code: http://testing.com/fil" />
<!-- message -->
<div id="post_message_510223" class="vb_postbit"><font color="green"><font size="3">Temp</font></font><br />
<br />
<br />
<img src="http://sample/test.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /><br />
<br />
<br />
info!<br />
<br />

<div style="margin:20px; margin-top:5px">
<div class="smallfont" style="margin-bottom:2px">Code:</div>
<pre class="alt2" dir="ltr" style="
margin: 0px;
padding: 6px;
border: 1px inset;
width: 470px;
height: 34px;
text-align: left;
overflow: auto">http://www.sample1.com/part1.html
http://www.sample1.com/part1.html
http://www.sample1.com/part1.html</pre>
</div><br />

<div class="smallfont" style="margin-bottom:2px">Code:</div>
<pre class="alt2" dir="ltr" style="
margin: 0px;
padding: 6px;
border: 1px inset;
width: 470px;
height: 1490px;
text-align: left;
overflow: auto">http://www.sample1.com/part1/sample_code.part01.rar
http://www.sample1.com/part1/sample_code.part01.rar</pre>

</div></div>
I want all the values that are after Code:</div> and between pre tags.
eg http://www.sample1.com/part1.html
http://www.sample1.com/part1.html
http://www.sample1.com/part1.html
and
http://www.sample1.com/part1/sample_code.part01.rar
http://www.sample1.com/part1/sample_code.part01.rar

Please note that at the start in meta tag there is also string Code: and I don't value from it.
Thanks in advance
Regards
