java读取xml的有关问题

java读取xml的问题
xml如下：
<?xml version="1.0" encoding="GB2312"?><root>
  <data>
  <list0>SJCZ_INFO</list0>
  <list1>QXCZ_INFO</list1>
  <list2>USER_INFO</list2>
  <list3>DEPT_INFO</list3>
  <list4>COMP_INFO</list4>
  </data>
</root>
我写得读取方法：
public void ReadXml(String path){
  try {
File file = new File(path);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
org.w3c.dom.Document document = builder.parse(file);
NodeList nl = document.getElementsByTagName("data");
for (int i = 0; i < nl.getLength(); i++) {
System.out.println(document.getElementsByTagName("list"+String.valueOf(i)).item(i).getFirstChild().getNodeValue());
  System.out.println("读取xml成功！");
}
} catch (Exception e) {
e.printStackTrace();
}
}
结果只有：SJCZ_INFO。是不是我nodelist取得有问题，该怎么取才可以循环？？

[解决办法]

Java code

几行代码。。    // w3c读取xml    @SuppressWarnings("unchecked")    public static void readXML4() {        File f = new File("f:/test.xml");        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();        DocumentBuilder builder;        try {            builder = factory.newDocumentBuilder();            org.w3c.dom.Document doc = builder.parse(f);            NodeList nl = doc.getElementsByTagName("data");            for (int k = 0; k < nl.getLength(); k++) {                System.out.println(nl.item(k).getTextContent());            }        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }
