如何在java中获取嵌套XML中的父标签？

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.parse("path/to/your/xml/file.xml");

Element rootElement = document.getDocumentElement();

NodeList parentNodes = rootElement.getElementsByTagName("parentTagName");
for (int i = 0; i < parentNodes.getLength(); i++) {
    Element parentElement = (Element) parentNodes.item(i);
    // 进一步处理父标签
}
