Add the below snippet to your functions.php file in your theme folder and every time you edit or add a new post or page a new sitemap.xml file will be generated in the root folder of your website for crawlers to access and index your site structure. Be sure to add custom post types to the 'post_type' arguments.

Generate XML Sitemap (functions.php
content_copyfile_download
add_action('publish_post', 'create_sitemap');
add_action('publish_page', 'create_sitemap');

function create_sitemap() {
  $sitemap_posts = get_posts(array(
    'numberposts' => -1,
    'orderby' => 'modified',
    'post_type'  => array('post','page'), // Add custom post types here
    'order'    => 'DESC'
  ));

  $sitemap = '<?xml version="1.0" encoding="UTF-8"?>';
  $sitemap .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';

  foreach($sitemap_posts as $post) {
    setup_postdata($post);

    $postdate = explode(" ", $post->post_modified);

  	$sitemap .= '<url>'.
      '<loc>'. get_permalink($post->ID) .'</loc>'.
      '<lastmod>'. $postdate[0] .'</lastmod>'.
      '<changefreq>monthly</changefreq>'.
    '</url>';
  }
  $sitemap .= '</urlset>';

  $fp = fopen(ABSPATH . "sitemap.xml", 'w');
  fwrite($fp, $sitemap);
  fclose($fp);
