Answer 1

我已经有一段时间了解Muenchian方法（Jeni Tennison might be useful here for reference）。

我对Muenchian方法的理解很简单就是＆＃34;＆lt; xsl：key＆gt;＆＃34;创建一种查找表。具有相同值的每个元素将具有相同的键值。因此，您可以通过将元素与其类型的第一个键进行比较，将元素分组到文档的不同部分。（这是对的吗？这有意义吗？）

我不确定我是否可以完全解释或理解它。但是，你有：

<xsl:key name="Collection_Id" match="*" use="av:Collection_Id" />

将此更改为：

<xsl:key name="Collection_Id" match="av:Detail[@Id]" use="av:Collection_Id" />

似乎解决了这个问题。
