*Element 節・Element 界面 (DOM)

[2] [CODE(DOMi)[Element]] 界面は、 [[HTML]]・[[XML]]
の[[要素]]のための機能を提供します。1つの [CODE(DOM)[Element]]
節が HTML/XML 文書の1つの要素に対応します。

[1] [[DOM1]] では、[RUBYB[要素節] [[CODE(DOM)[Element]] node]]は次の種類の[[節]]を子供に出来ます。
-[[Element]]
-[[Text]]
-[[Comment]]
-[[ProcessingInstruction]]
-[[CDATASection]]
-[[EntityReference]]

-[4] Method [CODE(DOMm)[normalize]] は、 DOM 2
で界面 [CODE(DOMi)[Node]] に移動しました。
- [5] [CODE(DOMi)[Node]] 界面では [CODE(DOMm)[[[hasAttributes]]]] method も定義されています (DOM 2)。 [CODE(DOMm)[hasAttribute]] との違いに注意。
