如何使用具有相同名称的标记在Java中遍历XML

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

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

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

Node root = document.getDocumentElement();

NodeList nodeList = root.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    // 进行相关操作，如获取节点名称、属性、文本内容等
}

<root>
    <tag>Tag 1</tag>
    <tag>Tag 2</tag>
    <tag>Tag 3</tag>
</root>

Document document = builder.parse("path/to/xml/file.xml");
Node root = document.getDocumentElement();
NodeList nodeList = root.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node.getNodeType() == Node.ELEMENT_NODE && node.getNodeName().equals("tag")) {
        System.out.println(node.getTextContent());
    }
}

Tag 1
Tag 2
Tag 3
