Description:
------------
preg_replace has a bug
//CASE STUDY: remove multiple instances of inside <table> <div
id="Paginator"> <span></span> <a href="#"></a>
</div></table>
$m = "¬";//Any marker that isn't currently in the strHTML string. Note,
this is an example, but you should use a function that gets a safeMarker.
// replaces all instances of </table> with </table>¬
$strHTML = preg_replace('/(<\/table>)/','$1'.$m, $strHTML);
//looks for all within <table><div id="Paginator"> and removes
them
//This would be the code to use but php seems to be greedy and doesn't
match all instances and only gets the last , where as perl, .NET or
javascript regular expressions would
$strHTML =
preg_replace('/(\<div\sid\=\"Paginator\"\>[^\¬]*)\&nbps\;/','$1',
$strHTML);

javascript regular expressions would
$strHTML = preg_replace('/(\<div
id\=\"Paginator\"\>[^\¬]*)\&nbps\;/','$1', $strHTML);
