I’ve created a script to dump my blog post history into an XML file suitable for Google Sitemaps. Note that I consider any XML-building script that does not use XML creation tools to be a hack. This is a hack.
<?php
header("Content-type: application/xml");
require_once( dirname(__FILE__) . '/wp-config.php'); // get the wordpress functions
// sitemap header
echo '<'.'?xml version="1.0" encoding="UTF-8"?>';
echo '<urlset xmlns="http://www.google.com/schemas/sitemap/0.84">';
// set upper limit to a sufficiently high number
$posts = get_posts('numberposts=32767&order=ASC&orderby=post_date');
// output all the posts
foreach($posts as $post): setup_postdata($post);
?>
<url>
<loc><?php the_permalink(); ?></loc>
<lastmod><?php echo get_post_modified_time('Y-m-d') ?></lastmod>
</url>
<?php
endforeach;
echo '</urlset>';
?>Example: sitemap.php.
I also add a rewrite condition to my .htaccess file:
RewriteRule ^sitemap.xml$ sitemap.php [L]Thus is born sitemap.xml.
