newForXml
Parses @xml_data and returns a #GDBusNodeInfo representing the data.
The introspection XML must contain exactly one top-level <node> element.
Note that this routine is using a glib-Simple-XML-Subset-Parser.description-based parser that only accepts a subset of valid XML documents.
Return
A #GDBusNodeInfo structure or null if @error is set. Free with g_dbus_node_info_unref().
