求一个简单的xml树

flyskytoday 2004-10-08 11:56:16

求一个简单的dom解析xml的三级菜单(叶菜单能够带链接)
开始时为缩进菜单(点击时:同一个父窗口的子菜单只能一个打开)
起码有三个文件组成xml,htm,css(或是xsl)

这几天一直看,心也定不下来,没什么头绪
今天又上班,才想起还有重要的没搞明白

最好有说明

看吧,如果做得好加你一百分:)

现在大概算是明白了怎么一回事,,,
谢谢楼上地热心回答

PS:
其中也问了不少人,不过没有几个认真回答你或是根本不回答
有些人还好一点,可能会认真教你,教你看什么
有些人跟本不会和你讲有点郁闷哦
还是靠自己吧:)
