读取XML文件中的特定节点-使用JAVA

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

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;
        String value = element.getTextContent();
        // 处理节点的值
    }
}
