Sitemap autoupdate <lastmod> ?

[Halfdeck]

One way is to render sitemap.xml using PHP

(.htaccess)

AddType application/x-httpd-php .xml

Then inside your XML file:

<?php
$lastmod = date('Y-m-d');
$header .= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
$header .= "<urlset xmlns=\"http://www.google.com/schemas/sitemap/0.84\"
	xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"
	xsi:schemaLocation=\"http://www.google.com/schemas/sitemap/0.84
	http://www.google.com/schemas/sitemap/0.84/sitemap.xsd\">";
echo $header;
?>

then include $lastmod in XML:

<url><loc>http://www.example.com</loc>
<lastmod><? echo $lastmod; ?></lastmod></url>

Problem with this approach is all your XML files in the root directory will not show correctly in many browsers.
