如何使用“insref”和“pref”对下面的元素进行分组我曾尝试在 xslt 版本 1 中使用生成密钥 ID。
XML：

期望的结果：
TITLE ARTIST ID INSREF PREF Qty
Empire Burlesque Bob Dylan 1 10
Hide your heart Bonnie Tyler 2 20 1 1
Lonly heart Bonnie Tyler 3 520 1 1
Still got the blues Gary Moore 4 56 1 1
Still got the blues Gary Moore 4 56 2 3
Maggie May Rod Stewart 8 78 2 1
Romanza Andrea Bocelli 9 45 1 1
Romanza Andrea Bocelli 10 45 2 1
这就是我所拥有的。我也在使用密钥生成功能。知道这个 xslt 有什么问题。至于计数，我正在考虑获得唯一键计数。
