本文整理了Java中com.sun.org.apache.xpath.internal.XPath类的一些代码示例，展示了XPath类的具体用法。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类的具体详情如下：
包路径：com.sun.org.apache.xpath.internal.XPath
类名称：XPath

XPath介绍

[英]The XPath class wraps an expression object and provides general services for execution of that expression.
[中]XPath类包装一个表达式对象，并为该表达式的执行提供一般服务。

代码示例

代码示例来源：origin: org.freemarker/freemarker

XPath xpath = new XPath(xpathQuery, null, customPrefixResolver, XPath.SELECT, null);
int ctxtNode = xpathContext.getDTMHandleFromNode(node);
XObject xresult = xpath.execute(xpathContext, ctxtNode, customPrefixResolver);
if (xresult instanceof XNodeSet) {
  NodeListModel result = new NodeListModel(node);

 *
 * @throws javax.xml.transform.TransformerException if syntax or other error.
 */
