XML问题[WebService]

我给你提供一个解析xml的实例,看你可不可以把他套到你的方法里了,实际上解析xml核心只有7步:
1.得到DOM解析器的工厂实例
2.从DOM工厂获得DOM解析器
3.把要解析的XML文档转化为输入流，以便DOM解析器解析它(也可以用File来处理)
4.解析XML文档的输入流，得到一个Document
5.得到XML文档的根节点
6.得到节点的子节点(5,6两步也可以像我例子中那样直接得到需要遍历的子节点,根据实际情况灵活应变)
7.循环遍历子节点,获得其属性值
到此解析完毕,xml文档解析博大精深,呵呵,应对方法也有很多,我提供的是最基础的dom解析,希望有用!

以上提供了解析的xml原文件,和负责解析的java源码.xml文档有些冗余,我删掉了一部分,没办法,希望能对你有帮助!

解析XML可以不要讨论了，下面的可以说说对 web service 的认识嘛

那就不知道了,网上查查吧,归根结底不是还是解析xml吗?

向楼主推荐此文章，有一些介绍。
