Java lib或应用程序将CSV转换为XML文件？[已关闭]

也许这可能会有所帮助：JSefa

您可以使用此工具读取 CSV 文件并将其序列化为 XML。

与上面的其他人一样，我不知道任何一步到位的方法，但是如果您准备使用非常简单的外部库，我会建议：

用于解析 CSV 的 OpenCsv（小巧、简单、可靠且易于使用）

Xstream解析/序列化XML（非常非常易于使用，并创建完全人类可读的xml）

使用与上面相同的示例数据，代码将如下所示：

package fr.megiste.test;

import java.io.FileReader;
import java.io.FileWriter;
import java.util.ArrayList;
import java.util.List;

import au.com.bytecode.opencsv.CSVReader;

import com.thoughtworks.xstream.XStream;

public class CsvToXml {     

    public static void main(String[] args) {

        String startFile = "./startData.csv";
        String outFile = "./outData.xml";

        try {
            CSVReader reader = new CSVReader(new FileReader(startFile));
            String[] line = null;

            String[] header = reader.readNext();

            List out = new ArrayList();

            while((line = reader.readNext())!=null){
                List<String[]> item = new ArrayList<String[]>();
                    for (int i = 0; i < header.length; i++) {
                    String[] keyVal = new String[2];
                    String string = header[i];
                    String val = line[i];
                    keyVal[0] = string;
                    keyVal[1] = val;
                    item.add(keyVal);
                }
                out.add(item);
            }

            XStream xstream = new XStream();

            xstream.toXML(out, new FileWriter(outFile,false));

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

生成以下结果：（Xstream 允许对结果进行非常精细的调整...）
