I found a great plug-in for generating XML sitemaps on WordPress sites. You can download the plug-in here: http://wordpress.org/extend/plugins/google-sitemap-generator/.
On top of generating an XML sitemap and placing it in your root folder, it also notifies: Google, Bing, and Ask each time you regenerate the XML sitemap.
I highly recommend this plug-in if you’re using WordPress.
