使用Java将CSV文件转换为XML文件

我正在尝试编写一个Java程序，该程序将读取不同公交车站信息的csv文件并将其转换为xml文件并另存为新的xml文件。我从朋友那里获得了一些代码方面的帮助，但由于他们忘记在代码中包含注释，因此无法理解问题出在哪里。修复代码的任何帮助将不胜感激。代码如下所示。

public class converter {
protected DocumentBuilderFactory domFactory = null;
protected DocumentBuilder domBuilder = null;

public static void main(String[] args) {



    ArrayList<String> busStopInfo = new ArrayList<String>(7);

    File file = new File("stops.csv");
    BufferedReader readFile = null;
    try {
        DocumentBuilderFactory df = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = df.newDocumentBuilder();

        Document document = db.newDocument();

        Element rootElement = document.createElement("BusStops");

        document.appendChild(rootElement);
        readFile = new BufferedReader(new FileReader(file));
        int line = 0;

        String information = null;
        while ((information = readFile.readLine()) != null) {

            String[] rowValues = information.split(",");

            if (line == 0) {
                for (String columnInfo : rowValues) {
                    busStopInfo.add(columnInfo);
                }
            } else {
                Element childElement = document.createElement("details");
                rootElement.appendChild(childElement);


                for (int columnInfo = 0; columnInfo < busStopInfo.size(); columnInfo++) {

                    String header = busStopInfo.get(columnInfo);
                    String value = null;

                    if (columnInfo < rowValues.length) {
                        value = rowValues[columnInfo];
                    } else {
                        value = " ";
                    }

                    Element current = document.createElement(header);
                    current.appendChild(document.createTextNode(value));
                    childElement.appendChild(current);
                    System.out.println(value);
                }
            }
            line++;
        }
    Transformer tf = TransformerFactory.newInstance().newTransformer();
tf.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tf.setOutputProperty(OutputKeys.INDENT, "yes");
Writer output = new StringWriter();
tf.transform(new DOMSource(document), new StreamResult(output));
System.out.println(output.toString());
} catch (Exception e) {

    }
} 

}

以下是csv文件的摘录

这是我要复制的xml文件的架构
