Yep did it using this method..
Ended up using a half hours worth of work in php.
Next, what I'll do is create a kml on the fly in this same php script
and update this on the user side via. ajax when the kml has been
created.
PHP script included below in case anyone ever has teh same problem
(unlikely - but you never know)
<?php
$x = $_GET['x'];
$y = $_GET['y'];
$xml = simplexml_load_file("doc.kml");
foreach($xml->Document->Folder->Placemark as $child)
{
$coordinates = explode(" ",$child->Polygon->outerBoundaryIs-
>LinearRing->coordinates);
$i = 0;
foreach($coordinates as $coordinate)
{
$individual = explode(",",$coordinate);
$current[$i] = $individual;
$i++;
}
if($x > $current[0][0] && $y > $current[0][1])
{
if($x < $current[1][0] && $y > $current[1][1])
{
if($x < $current[2][0] && $y < $current[2][1])
{
if($x > $current[3][0] && $y < $current[3][1])
{
echo $child->name . "<br />";
}
}
}
}
}
?>
