No, because it does not have `type="array"`. So it will be of type cdata 
and will be returned as string.

It is possible to create such structure. See bug report for example.

In fact existing code works if <meta> exists but not as array. Mine 
fixes a case when it does not exist at all:

>> +			} elseif (!isset($editData['meta']) || !is_array($editData['meta']))	{
