The following code will recurse down a directory tree, generating a sitemaps.org compatible sitemap.xml file. You can submit this to google, yahoo, and microsoft, and control how they index your files (including finding links to files that aren't available through text links the spider can read. The protocol names the resources and tells the spider the last time they were modified, improving search spider efficiency.
It respects a set of properties (which inherit, so you only need to set them at a folder level to change the elements within):
- sitemap_hidden : Hides the resource from the sitemap
- sitemap_priority : sets the prioertiy field (1 by default if not otherwis set)
- sitemap_change_frequency : how often the resource changes (weekly by default)
