Last but not least, and sorry for reviving this thread, the queries are case sensitive.

In other words, if you look for meta name="description"... or "meta name="keywords", it will not find "meta name="Description"... or "meta name="Keywords"... respectively. So careful with that!

And I can tell you, after working a while with xdom and metatags, eventually I believe that the best approach for that is to use this function: http://php.net/manual/es/function.get-meta-tags.php
