java将字符串写到xml某节点中

config.ini

[eyoowon]
actiOnparam= update\_eyoowon.exe
ver = 1.0.0.3
name = eyoowon.zip
action = 3
md5 = 
businesses =

1.xml

从config.ini文件中读取businesses的值放到1.xml的businesses节点中

Element businesses = null;

Document docu = DocumentHelper.parseText(business); // 将字符串转为XML
 Element rootElt = docu.getRootElement(); // 获取根节点
if(root.element("businesses")==null){
businesses=root.addElement("businesses");
}
businesses.add(rootElt);

ServletContext sc = ServletActionContext.getServletContext();
String path = sc.getRealPath("1.xml");
OutputFormat format = OutputFormat.createPrettyPrint();
format.setEncoding("UTF-8");
FileOutputStream fos=new FileOutputStream(new File(path));
XMLWriter writer=new XMLWriter(fos,format);
writer.write(root);
writer.close();
