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

Node.hasAttributes介绍

[英]Returns whether this node (if it is an element) has any attributes.
[中]返回此节点（如果是元素）是否具有任何属性。
