本文整理了Java中org.w3c.dom.Node.getParentNode()方法的一些代码示例，展示了Node.getParentNode()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.getParentNode()方法的具体详情如下：
包路径：org.w3c.dom.Node
类名称：Node
方法名：getParentNode

Node.getParentNode介绍

[英]The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
[中]此节点的父节点。除Attr、Document、DocumentFragment、Entity和Notation之外的所有节点都可能有父节点。但是，如果节点刚刚创建，尚未添加到树中，或者已从树中删除，则此值为[$5$]。
