从xpath中查找字符串，该路径包含标记作为Java中的子元素

import javax.xml.xpath.*;
import org.w3c.dom.*;

public class XPathExample {
    public static void main(String[] args) throws Exception {
        // 创建XPath对象
        XPath xpath = XPathFactory.newInstance().newXPath();
        
        // 解析XML文档
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse("path/to/xml/file.xml");
        
        // 编译XPath表达式
        XPathExpression expr = xpath.compile("//element[contains(text(),'字符串')]");
        
        // 执行XPath查询
        NodeList nodes = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
        
        // 遍历查询结果
        for (int i = 0; i < nodes.getLength(); i++) {
            Node node = nodes.item(i);
            System.out.println(node.getTextContent());
        }
    }
