[Plugin: Google News Sitemap Generator] Google News Parsing Error – Not Well Formed

I suspect your permalink has a character in it which annoys your XML parser.

If you still had that sitemap, running something like the unix xmllint over it would identify the field in question and allow you to ensure the problem is solved.

(I’m suggesting the permalink field as this seems to be the only one which isn’t escaped with htmlspecialchars… perhaps I’ll rewrite it.
