如何在Java中递归地读取xml属性中的数据并将其存储在CSV中

import org.w3c.dom.*;

public class XMLParser {
    public static void main(String[] args) {

            // 创建DOM解析器
            DocumentBuilder builder = factory.newDocumentBuilder();
            // 解析XML文件
            Document document = builder.parse(new File("input.xml"));
            
            // 获取根节点
            Element root = document.getDocumentElement();
            
            // 创建CSV文件
            FileWriter csvWriter = new FileWriter("output.csv");
            
            // 递归遍历XML节点
            traverseNode(root, csvWriter);
            
            // 关闭CSV文件
            csvWriter.close();
            
            System.out.println("XML属性已成功存储在CSV文件中。");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    private static void traverseNode(Node node, FileWriter csvWriter) throws IOException {
        // 检查节点类型
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            // 获取节点的属性
            NamedNodeMap attributes = node.getAttributes();
            
            // 遍历属性
            for (int i = 0; i < attributes.getLength(); i++) {
                Node attribute = attributes.item(i);
                String attributeName = attribute.getNodeName();
                String attributeValue = attribute.getNodeValue();
                
                // 将属性写入CSV文件
                csvWriter.append(attributeName).append(",").append(attributeValue).append("\n");
            }
        }
        
        // 递归遍历子节点
        NodeList children = node.getChildNodes();
        for (int i = 0; i < children.getLength(); i++) {
            Node child = children.item(i);
            traverseNode(child, csvWriter);
        }
    }
