这是我的输入 xml 并期望输出如下所示。

agent number :1 (sorted order)  
PendingIssues:yes(if yes)

product type: 1

policy number:445(sorted order)
annual premium:12000.0

policy number:446
annual premium:12000.0

sub total pending:24000(12000+12000)        

PendingIssues:yes(if yes)
product type: 2

policy number:555
annual premium:12000.0

policy number:556
annual premium:12000.0

sub total pending:24000(12000+12000)


AfterBusinessIssues:yes(if yes)

product type: 1

policy number:445
annual premium:12000.0

policy number:446
annual premium:12000.0

sub total after business:24000(12000+12000) 

AfterBusinessIssuess:yes(if yes)            

product type: 2

policy number:445
annual premium:12000.0

policy number:446
annual premium:12000.0

sub total after business:24000(12000+12000).

应为所有代理编号重复此操作。

grand total :sub total pending(all)+sub total after business(all)=24000(12000+12000)+24000(12000+12000)=48000

此处代理编号和保单编号应按排序顺序排列。之前我发布了相同类型的 xml。我得到了答案，但现在这对我来说有些挑战，请任何人帮助我。

共享 xsl 请在我做错的地方进行更正。谢谢。
