XSL循环在每个级别上均无法正确进行

我需要循环访问此SAP IDOC以报告货运数据。我需要中断G07节点（包装）中E2EDT37_KDMAT（零件号），E2EDT37_VHILM_KU（包装类型）和E2EDT37_QUANTITY的每次更改。当前的代码似乎一直有效，直到G01（SHIPMENT）节点中有多个G16（DELIVERY）节点为止。

此代码段不会产生XML输出，并且在消息输出中会看到该问题。

我认为我尝试的方法无效，我会找到另一种方法。但是我不明白为什么。我已经尝试了在前同级而不是在前，只是得到了不同的错误输出。

每个循环使用与最后一个相同的谓词，并添加一个或多个条件，以标识所有与E2EDT37记录匹配的内容，并对E2EDT37_KDMAT，E2EDT37_VHILM_KU和最后的E2EDT37_QUANTITY的每个唯一值执行一次下一条语句。它似乎非常接近，但是永远无法解决问题。我对E2EDT37_KDMAT [not（。= preceding :: E2EDT37_KDMAT）]在这里工作的方式有何误解？

结果输出

1）在Create_Outer_PAC交货中：0037371484

2）对于每个Outer_PAC：505059227

3）对于每个E2EDT37_KDMAT：6561143独特的KDMAT在这里很不错

我在这里找到并显示了一个匹配的VHILM_KU，但是尝试在每个VHILM_KU处循环的下一行不会出现与xsl：message相同的Xpath

<xsl:for-each select="/ACTIS/G01/G07/E2EDT37[E2EDT37_PACK_TYPE='INNER'][E2EDT37_PARENT=$Pallet/E2EDT37_EXIDV][E2EDT37_DELIVERY=$current-delivery][E2EDT37_KDMAT=$current-part]/E2EDT37_VHILM_KU[not(.=preceding::E2EDT37_VHILM_KU)]"> 

<E2EDT37_VHILM_KU>0000SON</E2EDT37_VHILM_KU>

    No For each E2EDT37_VHILM_KU break on E2EDT37_VHILM_KU=0000SON

1）在Create_Outer_PAC交货中：0037371519

2）对于每个Outer_PAC：505059227

3）对于每个E2EDT37_KDMAT：6561111 

<E2EDT37_VHILM_KU>0000SON</E2EDT37_VHILM_KU>

    This one breaks as expected.  You see we have an E2EDT37_VHILM_KU found with value 0000SON in the line above here.

尽管我们也找到并显示了与0000SON相同的E2EDT37_VHILM_KU，但我没有在上面的第一个for-each循环中看到此消息。

我们有两个E2EDT37段，其KDMAT值为6561143和6561141。第一个循环按预期在每个唯一的KDMAT处中断。

4）对于每个E2EDT37_VHILM_KU：0000SON

5）对于每个E2EDT37_QUANTITY：8500.000

在使用谓词[E2EDT37_PACK_TYPE ='INNER'] [E2EDT37_PARENT = $ Pallet / E2EDT37_EXIDV] [E2EDT37_DELIVERY = $当前交付] [E2EDT37_KDMAT = $当前部分]？我以为那是我错的地方，但是范式对我来说还不清楚。消息输出显示Xpath确实找到了一个VHILM_KU。下一个具有相同Xpath的for-each语句什么也找不到。

更清晰或更令人困惑吗？
