用DOM读取XML文件例子（JAVA）

        Document document = null;
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
{
            DocumentBuilder builder = factory.newDocumentBuilder();
            document = builder.parse(configPath);
            Node rootNode = document.getFirstChild();
            System.out.println(rootNode.toString());
            NodeList logFileList = rootNode.getChildNodes();
{
                Node curNode = logFileList.item(i);
                System.out.println("Log file" + i + " : " + curNode.toString());
                NamedNodeMap map = curNode.getAttributes();
{
                    System.out.println("Log file" + i + " :key: " + map.item(j).getNodeName());
                    System.out.println("Log file" + i + " :value: " + map.item(j).getNodeValue());
                }
                NodeList columns = curNode.getChildNodes();
{
                    System.out.println("column" + j + " : " + columns.item(j).toString());
                }
            }
{
            e.printStackTrace();
{
            e.printStackTrace();
{
            e.printStackTrace();
        }

XML文件内容：

<?xml version="1.0" encoding="UTF-8"?>
<LOG_MAPPING>
    <LOG_FILE fileNamePattern="ad.+\.log" class="com.nec.jp.bigm.log.ADLogCounter">
        <column name="date"/>
        <column name="carrier"/>
        <column name=""/>
    </LOG_FILE>
    <LOG_FILE fileNamePattern="access.+\.log" class="com.nec.jp.bigm.log.ADLogCounter">
        <column name=""/>
        <column name=""/>
        <column name=""/>
    </LOG_FILE>
</LOG_MAPPING>
