如何在Java中读取XML DOM对象中的特定节点？

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;
import org.w3c.dom.NodeList;

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

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

Element root = document.getDocumentElement();

NodeList nodeList = root.getElementsByTagName("node_name");

for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node.getNodeType() == Node.ELEMENT_NODE) {
        Element element = (Element) node;
        // 获取节点的值
        String value = element.getTextContent();
        // 获取节点的属性值
        String attributeValue = element.getAttribute("attribute_name");
        // 进行相应的处理
    }
}
