Groovy 动态修改XML

我现在grails+groovy，用Groovy 生成 Flex tree 功能树需要的XML文件，里面用到了递归，可以无限级。下现有二个类：一个是对象TabFunction,这就是我的功能表影射出的对象，Test3是生成XML的测试类。(附件中有:groovy语方法文档。)

package ce.bean

class TabFunction {

String cCode;

String cName;

String cDescription;

String cParentCode;

Date dCreate=new Date();

String cState;

String cGrade

static mapping ={

version false;

}

static constraints = {

}

}

package com

import groovy.xml.StreamingMarkupBuilder

import ce.bean.TabFunction

class Test3 {

def str="<funlist></funlist>";

def void roolMothed(){

def obj= new TabFunction(cCode:"TOP_SysUserManager",cName:"基础信息维护",cDescription:"系统注册信息管理",cState:"0",cGrade:1,cParentCode:"00");

obj.id=2;

def obj1= new TabFunction(cCode:"SYS_UserManager",cName:"用户信息管理",cDescription:"系统注册用户管理",cState:"0",cGrade:2,cParentCode:"TOP_SysUserManager");

obj1.id=1;

def obj2= new TabFunction(cCode:"TOP_SystemManager",cName:"系统信息维护",cDescription:"系统注册信息管理",cState:"0",cGrade:1,cParentCode:"00");

obj2.id=3;

def obj3= new TabFunction(cCode:"fff",cName:"系统信息维护",cDescription:"系统注册信息管理",cState:"0",cGrade:3,cParentCode:"SYS_UserManager");

obj3.id=5;

List list=new ArrayList();

list<<obj1<<obj<<obj2<<obj3;

println "LAST:::"+ testMethod(list,list,"00",str)

}

def String testMethod(all,list,parentCode,str){

def temp = all.findAll {[email protected]==parentCode};

def root = new XmlSlurper().parseText(str) ;

def outputBuilder = new StreamingMarkupBuilder()

def tempList=new ArrayList();

String result="";

if(parentCode.length()>0){

temp.each {

def tempFun=it;

//def obj=root.sysfun.find {[email protected] == parentCode };

root.appendNode{

sysfun(cCode:tempFun.cCode,cName:tempFun.cName);

}

def ll= all.findAll {[email protected]==tempFun.cCode}

if (ll.size()>0) ll.each{ tempList<<it};

}

}else{

list.each {

def tempFun=it;

// println tempFun.cParentCode+":::::"+tempFun.cCode;

def obj=root.'**'.find{[email protected]==tempFun.cParentCode};

obj.appendNode{

sysfun(cCode:tempFun.cCode,cName:tempFun.cName);

}

def ll= all.findAll {[email protected]==tempFun.cCode}

if (ll.size()>0) ll.each{ tempList<<it};

}

}

result = outputBuilder.bind{ mkp.yield root }

if(tempList.size()>0)

testMethod(all,tempList,"",result);

else{

return result;

}

}

public static void main(def a){

new Test3().roolMothed();

}

}
