对于XSL文件中没有重复节点的每个循环

因此，我有这个XML文件（下面），我试图按照Customer列出Reservations。由于客户是“内部”Reservations并且不是唯一的（多个客户可以执行不同的预订），所以我一直面临一个问题：我可以根据Customer检索合适的数量Reservations，但它们显示客户在文件，因为我每次都抛出所有Reservations ...对于XSL文件中没有重复节点的每个循环

你能帮我一下吗？我不需要发送到已经处理的HTML文件Customers。

这是一个*分组*问题 - 看到：HTTP：//www.jenitennison。 com/xslt/grouping/muenchian.html以及Muenchian在SO上的众多示例。 –

@ michael.hor257k谢谢，我已经尝试过使用它，但我遇到了一些问题...如果我在第一个for-each循环之前定义一个键，就像这个''，它说XSL无效......任何帮助？谢谢你，我是XSL新手... –

你应该发布你的尝试，所以我们可以修复它，而不是从头开始写所有东西。而不是 - 你显示的关键定义不会产生错误。 –

我们需要的最后一件事是Muenchian分组的另一个例子。但因为你似乎无法管理你自己，试试这样：

非常感谢！我不知道我们可以在'for-each'中使用这个键！再次感谢你：） –
