Can someone explain why I might be getting this error in Google webmaster tools after I submit my sitemap? Both my sitemap and robots.txt file are accessible in the root of my site at http://www.zybrononline.com/sitemap.xml and http://www.zybrononline.com/robots.txt. The robots.txt file just points to my sitemap and is set to allow all. I submitted the same sitemap (with a few less urls) just a few days ago with no issue and now I'm getting this error every time I try to submit it.
zybron, I am not sure, but it seems you are missing the declarations before the <urlset> tag ... Check out the sitemap FAQ at http://forums.digitalpoint.com/showthread.php?t=531765 K
