This week I added support for Google Sitemaps to my blog. While this isn't in the core BlogCFC install yet, I thought I'd share the code in case others wanted to do it. Right now I've just created a new CFM and dropped the code in there. I will most likely move the generation to a CFC method later on. Also note that I was unable to get the sitemap to verify until I "tricked" google. My file name was, let's say, sitemap.cfm. This refused to validate. I saved the output of my file as test.xml, and that validated immidiately. I hunted around and found a few people who asked if the extension would cause problems for Google. On a whim, I resubmitted by sitemap with this url: http://ray.camdenfamily.com/sitemap.cfm?ext=xml. (Not the real URL.) This was enough to "fool" Google and allow my sitemap to validate. The code is below.
Note - the code belows has MY url in it. You would obviously want to change that. The "real" code in 4.0 won't require that.
