プロパティ

childElementCount

子要素の数。

firstElementChild

最初の子要素。存在しない場合は null になります。

lastElementChild

最後の子要素。存在しない場合は null になります。

nextElementSibling

次の兄弟要素。存在しない場合は null になります。

previousElementSibling

前の兄弟要素。存在しない場合は null になります。

schemaTypeInfo

未実装。常に null を返す。

tagName

要素名

className

スペースで分割された、要素のクラスを表す文字列

id

"id" 属性を通して反映される要素のID

変更履歴

バージョン 説明
8.3.0 プロパティ className と id, メソッド DOMElement::getAttributeNames(), DOMElement::insertAdjacentElement(), DOMElement::insertAdjacentText(), DOMElement::toggleAttribute() が追加されました。
8.0.0 プロパティ firstElementChild, lastElementChild, childElementCount, previousElementSibling, nextElementSibling が追加されました。
8.0.0 DOMElement は、 DOMParentNode と DOMChildNode を実装しました。

注意

注意:

DOM拡張モジュール は UTF-8 エンコーディングを使います。他のエンコーディングを扱う場合は、mb_convert_encoding(), UConverter::transcode(), iconv() を使ってください。
