使用jdom创建xml

1.首先当然是jar包了，下载地址：http://www.jdom.org/dist/binary/ 下面的jdom-1.1.1.zip下载下来，解压开找到build目录下的jdom.jar

2.添加jdom.jar到项目中，别忘了buildpath

3.生成xml文件方法：

public static void createXMLFile() throws FileNotFoundException, IOException, SQLException{
        RegionDao regionDao = new RegionDao();
        String createXmlPath = "c:\\region.xml";
        Element regionRoot = new Element("region");
        Document document = new Document(regionRoot);
        
        List<Region> parentRegions = regionDao.getRegionByParentId(0);
        for(Region regioni:parentRegions){
            Element elements = new Element("province");
            elements.setAttribute("id",regioni.getId()+"");
            elements.setAttribute("name",regioni.getName().trim());

            System.out.println(regioni.getName().trim());
            elements = recursion(regioni.getId(), elements);
            
            regionRoot.addContent(elements);
        }
        
        XMLOutputter xo = new XMLOutputter();
        xo.output(document, new FileOutputStream(createXmlPath));
    }
