Ich verwende das Google Maps-API, um Markierungen anzuzeigen, die aus einer mySQL-Datenbank abgerufen werden.Google Maps-API-Seite wird nicht geladen - Pars XML-Fehler
Ich bin mit dem WampServer Stapel, auf localhost, und immer diese Fehlermeldung:
This page contains the following errors:

ich den folgenden JS Code verwendet:

Heres die PHP-Datei, die eine erzeugt XML-Dokument:

$result = mysqli_query($db, $query);
if (!$result) {

header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysqli_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE

Beim Anzeigen der Quelle im Browser endet der Quellcode bei der Deklaration von:
function() {

});
