This is not a fancy regex, but you can get what you need using strpos and strrpos:

<?php

$xml = "map.centerAndZoom(new GPoint(-82.81649, 42.175552), 4)";

$start = 1+strrpos($xml, '(');
$end = strpos($xml, ')');

list($latitude, $longitude) = explode(', ', substr($xml, $start, ($end-$start)));

echo "Latitude: $latitude<br />";
echo "Longitude: $longitude<br />";

?>

In case the string position changes, you can try this:

<?
$str = '$xml = map.centerAndZoom(new GPoint(-82.81649, 42.175552), 4);';
$m = "/GPoint\(([\-0-9.]+), ([\-0-9.]+)\)/";
$a=array();
preg_match($m, $str, $a);
print_r($a);
?>
