.
InvalidStateError

SyntaxError
DOMException

or Attr
object.
The following types are also permitted as descendants of the root node, in addition to Node
and Attr
:
If any other type is encountered, a TypeError
exception is thrown.
There are some things worth noting about the XML output by serializeToString()

Element
and Attr
nodes are always serialized with their namespaceURI
