Sitemap autoupdate <lastmod> ?

[Den]

Is it possible to auto update the <lastmod> tag since my sites are updated daily?

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.

unfortunally google could not read my sitemap this is how it looks like

<?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;
?>
  <url>
      <loc>http://www.hentaiprince/</loc>
      <lastmod><? echo $lastmod; ?></lastmod>
      <changefreq>hourly</changefreq>
      <priority>0.9</priority>
   </url>
... and so on
</urlset>

You need to wrap the list of urls in <urlset>. You have </urlset> at the end but no opening <urlset>.

If that fix doesn't work, try validating it using an XML validator. Also use a http header checker to make sure the PHP page is generating the right code.

will fix it
