本文整理了Java中org.jdom2.xpath.XPath.newInstance()方法的一些代码示例，展示了XPath.newInstance()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。XPath.newInstance()方法的具体详情如下：
包路径：org.jdom2.xpath.XPath
类名称：XPath
方法名：newInstance

XPath.newInstance介绍

[英]Creates a new XPath wrapper object, compiling the specified XPath expression.
[中]创建新的XPath包装器对象，编译指定的XPath表达式。
