<p><code><strong>NonDocumentTypeChildNode</strong></code> 接口包含专属于某些（特殊） {{domxref("Node")}} 对象的方法，这些对象可以拥有父对象，但不适用于 {{domxref("DocumentType")}} 接口。</p>
<p><code>NonDocumentTypeChildNode</code> 是一个裸接口（raw interface），无法创建拥有此类型的对象；它是由 {{domxref("Element")}}，和 {{domxref("CharacterData")}} 对象实现的。</p>

<dd>Returns the {{domxref("Element")}} immediately prior to this node in its parent's children list, or <code>null</code> if there is no {{domxref("Element")}} in the list prior to this node.</dd>
