NonDocumentTypeChildNode

NonDocumentTypeChildNode 接口包含专属于某些（特殊） Node 对象的方法，这些对象可以拥有父对象，但不适用于 DocumentType 接口。

NonDocumentTypeChildNode 是一个裸接口（raw interface），无法创建拥有此类型的对象；它是由 Element，和 CharacterData 对象实现的。

属性

NonDocumentTypeChildNode.nextElementSibling 只读
Returns the Element immediately following this node in its parent's children list, or null if there is no Element in the list following this node.

方法

此接口既没有继承方法，又没有专有方法。
