プロパティ

implementation: このドキュメントを処理する DOMImplementation オブジェクト
doctype: このドキュメントに関連付けられた文書型宣言
URL: Equivalent to documentURI.
characterSet: The encoding of the document used for serialization. Upon parsing a document, this is set to the input encoding of that document.
inputEncoding: Legacy alias for characterSet.
charset: Legacy alias for characterSet.
documentURI: ドキュメントの位置。未定義の場合は null
documentElement: The Dom\Element that is the document element. This evaluates to null for document without elements.
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。
childElementCount: 子要素の数
body: The first child of the html element that is either a body tag or a frameset tag. These need to be in the HTML namespace. If no element matches, this evaluates to null.
head: The first head element that is a child of the html element. These need to be in the HTML namespace. If no element matches, this evaluates to null.
