将 Muenchian 分组应用于 XSLT
Applying Muenchian grouping to XSLT
对 xlst 完全陌生，我尝试通过许多链接来应用 Muenchian 分组但无济于事，很可能是因为我可能没有将额外的行放在正确的位置，并且不知道如何转换为 xlst2 以便改为使用 for-each-group。不管怎样，我要转换的 csv 文件非常简单：

让我从与您的问题无关但仍与主题相关的内容开始，恕我直言：您当前的样式表过于冗长。如评论中所述，使用 attribute value templates instead of xsl:attribute instructions. In addition, the first template is entirely redundant, as this is taken care of by the built-in template rules 可以显着减少它。还有其他一些事情。我冒昧地删除了所有不必要的冗长内容。
除此之外，这是 Muenchian grouping 的一个非常标准的实现 - 不确定您为什么会遇到这样的问题：

对 xlst 完全陌生，我尝试通过许多链接来应用 Muenchian 分组但无济于事，很可能是因为我可能没有将额外的行放在正确的位置，并且不知道如何转换为 xlst2 以便改为使用 for-each-group。不管怎样，我要转换的 csv 文件非常简单：

让我从与您的问题无关但仍与主题相关的内容开始，恕我直言：您当前的样式表过于冗长。如评论中所述，使用 attribute value templates instead of xsl:attribute instructions. In addition, the first template is entirely redundant, as this is taken care of by the built-in template rules 可以显着减少它。还有其他一些事情。我冒昧地删除了所有不必要的冗长内容。
除此之外，这是 Muenchian grouping 的一个非常标准的实现 - 不确定您为什么会遇到这样的问题：
