求例子，用JDOM处理XML文档

来源: 互联网发布时间：2015-08-03

本文导语: 有一些方法，比如给参数：elemnetname,attributename 返回：attributevlaue 再比如给参数：elementname,attributename,attributevalue 处理结果：在elementname中加入属性：attributename="attributevalue" 请大虾给几个例子，谢谢！ ...

有一些方法，
比如给参数：elemnetname,attributename
返回：attributevlaue

再比如
给参数：elementname,attributename,attributevalue
处理结果：在elementname中加入属性：attributename="attributevalue"

请大虾给几个例子，谢谢！
