这个是我现在的代码protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)

Answer 1

@TheDolphin   
如果不用xpath嘞？

Answer 2

首先不明白你的意思。。Repeater1 这个你是怎么绑定的。。你的这个控件里面再套控件。。这么麻烦。。
你一开始是怎么绑定Repeater1 的。然后这个事件只要根据绑定的 去匹配对应的节点xml有方法可以根据你给定的名称获取到对应的节点，而不需要整体的遍历。。你这个效率相当低啊。。

Answer 3

@紫魂  因为，我一部分的数据是放在数据库里面的，一部分数据是放在xml里面的，所以才用嵌套的
