类的具体详情如下:
包路径:org.jdom2.xpath.XPath
类名称:XPath
[英]A utility class for performing XPath calls on JDOM nodes, with a factory interface for obtaining a first XPath instance. Users operate against this class while XPath vendors can plug-in implementations underneath. Users can choose an implementation using either #setXPathClass or the system property "org.jdom2.xpath.class".
[中]用于在JDOM节点上执行XPath调用的实用程序类,带有用于获取第一个XPath实例的工厂接口。用户针对这个类进行操作,而XPath供应商可以在下面实现插件。用户可以选择使用#setXPathClass或系统属性“org.jdom2.xpath.class”的实现。
