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

XPath.execute介绍

[英]Given an expression and a context, evaluate the XPath and return the result.
[中]给定表达式和上下文，计算XPath并返回结果。

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
 * @xsl.usage experimental
