XSLT如何在Muenchian分组转换中递增？

我有一个分组转换，我想在其中包含一个计数/增量。如果指定了分组，则变换会对值进行分组。这些值是转换用于连接在一起的文件位置，以便将内容作为一个文件输出。如果没有指定分组，转换将使用该值获取文件内容，而不将其附加到任何内容

XSLT:

我试图做的是为总页面设置一个计数器，见下文，关于小节和小节，并将增量分配给。我尝试过param，但它需要递归模板？如果我加入sem来破坏其余的转换。使用模板时是否已创建“循环”

这似乎有正确的总数。显然，我没有要拉入的文件，因此内容都丢失了。

此XSLT 1.0样式表

替代解决方案是如何工作的？ 考虑键值中使用的Xpath表达式的重要部分

如果@group不存在或为空，那么这相当于

concat(
  substring-before(
    concat( generate-id(), '@@', generate-id()),
    '@@' ),
  @group
  )

concat(
  '',
  @group
  )

。。。或者

concat( generate-id(), @group)

generate-id()

@group

。。。或者

concat( generate-id(), @group)

generate-id()

@group

。。。每个节点都是唯一的，这就是我们想要的

但是如果@group不是空的，那么这相当于

concat(
  substring-before(
    concat( generate-id(), '@@', generate-id()),
    '@@' ),
  @group
  )

concat(
  '',
  @group
  )

。。。或者

concat( generate-id(), @group)

generate-id()

@group

允许将具有group属性的模块分组在一起
