本文整理了Java中org.w3c.dom.Node.isSameNode()方法的一些代码示例，展示了Node.isSameNode()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.isSameNode()方法的具体详情如下：
包路径：org.w3c.dom.Node
类名称：Node
方法名：isSameNode

Node.isSameNode介绍

[英]Returns whether this node is the same node as the given one.
This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
[中]返回此节点是否与给定节点相同。
此方法提供了一种确定实现返回的两个Node引用是否引用同一对象的方法。当两个Node引用是对同一对象的引用时，即使通过代理，这些引用也可以完全互换使用，这样所有属性都具有相同的值，并且对任一引用调用相同的DOM方法始终具有完全相同的效果。
