     The value of the name property becomes the key, the value of the
     content property becomes the value of the returned array, so you
     can easily use standard array functions to traverse it or access
     single values. Special characters in the value of the name
     property are substituted with '_', the rest is converted to lower
     case.  If two meta tags have the same name, only the last one
     is returned.
