我想将XML文件转换为CSV文件。所以我只是解析XML文件。现在我想将这个解析数据写入CSV文件。我不知道如何编写这个解析数据。所以请帮助我
<data399173_eff_sor>
<record>
<ID>1</ID>
<item_no>1.0</item_no>
<description>Hack off tiles and make good walls</description>
<price>100</price>
<base_qty>50</base_qty>
<var_qty>20</var_qty>
<base_price_>5000</base_price_>
</record>
<record>
<ID>1</ID>
<item_no>1.03</item_no>
<description>Test</description>
<price>45</price>
<base_qty>100</base_qty>
<var_qty>4500</var_qty>
<base_price_>0</base_price_>
</record>
</data399173_eff_sor>
Java代码:
public static void main(String argv[]) {
try {
File fXmlFile = new File("D:/formdata.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
NodeList nList = doc.getElementsByTagName("record");
System.out.println("----------------------------");
for (int temp = 0; temp < nList.getLength(); temp++) {
Node nNode = nList.item(temp);
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
System.out.println("Item No : " + eElement.getElementsByTagName("item_no").item(0).getTextContent());
System.out.println("Description : " + eElement.getElementsByTagName("description").item(0).getTextContent());
System.out.println("price : " + eElement.getElementsByTagName("price").item(0).getTextContent());
System.out.println("base qty : " + eElement.getElementsByTagName("base_qty").item(0).getTextContent());
System.out.println("Var qty : " + eElement.getElementsByTagName("var_qty").item(0).getTextContent());
System.out.println("Base price : " + eElement.getElementsByTagName("base_price_").item(0).getTextContent());
}
}
generateCsvFile("d:\\testCSV.csv");
} catch (Exception e) {
e.printStackTrace();
}
}
private static void generateCsvFile(String sFilename) {
// TODO Auto-generated method stub
try
{
FileWriter writer = new FileWriter(sFilename);
writer.flush();
writer.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
现在如何写这个解析数据?我只是创建generateCsvFile()函数来创建文件我不知道从正确的地方调用它

一种方法是使用commons-csv来写入数据。从测试代码:
final FileWriter sw = new FileWriter("myfile.csv");
final CSVPrinter printer = new CSVPrinter(sw, format);
for (int i = 0; i < nLines; i++) {
printer.printRecord(lines[i]);
}
printer.flush();
printer.close()
