java需要帮助来替换CSV中的XML标记内容

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class CSVXMLReplacer {
    public static void main(String[] args) {
        String csvFilePath = "path/to/csv/file.csv";
        String xmlTagToReplace = "<tag>";
        String replacementText = "replacement";

        try (BufferedReader reader = new BufferedReader(new FileReader(csvFilePath));
             BufferedWriter writer = new BufferedWriter(new FileWriter(csvFilePath + "_modified.csv"))) {

            String line;
            while ((line = reader.readLine()) != null) {
                String[] fields = line.split(",");

                for (int i = 0; i < fields.length; i++) {
                    fields[i] = fields[i].replace(xmlTagToReplace, replacementText);
                }

                String modifiedLine = String.join(",", fields);
                writer.write(modifiedLine);
                writer.newLine();
            }

            System.out.println("CSV file modified successfully.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
