Uwagi

Mimo że ta metoda tworzy nowy obiekt w kontekście dokumentu, nie dodaje automatycznie nowego obiektu do drzewa dokumentów. Aby dodać nowy obiekt, należy jawnie wywołać jedną z metod wstawiania węzła.

Zgodnie z zaleceniem W3C Extensible Markup Language (XML) 1.0 węzły tekstowe są dozwolone tylko w węzłach Element, Attribute i EntityReference.
