This should get you started:
<?
function callback($a){
print_r($a);
}
$str = <<<END
<BLOCK NAME="TOP">
(a bunch of markup code)
</BLOCK>
<BLOCK NAME="BOTTOM">
(a bunch of markup code)
</BLOCK>
<BLOCK NAME="WAYOVERHERE">
(a bunch of markup code)
</BLOCK>
END;
preg_replace_callback('!<BLOCK NAME="(.*?)">(.*?)</BLOCK>!is','callback',$str);
Use the call back function to build whatever you need.
