Java 解析 XML 字符串并拆分 Device 节点内容

以下是用 Java 处理字符串格式的 XML 信息并拆分每个 '' 内容的示例代码：

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import java.io.ByteArrayInputStream;

public class XMLParser {
    public static void main(String[] args) {
        String xml = "<Organization>
" + "<Department>
" + "</Department>
" + "<Devices>
" + "<Device></Device>

注意：示例代码使用了 Java 的内置 XML 解析库，需要引入相关的库文件。

您也可以使用其他 XML 解析库，例如 JDOM 或 DOM4J，来完成同样的功能。
