XSLT 2.0 根据条件删除元素并在每个组中复制其余部分
XSLT 2.0 remove elements based on condition and copy rest within for-each-group
我希望按原样复制输入 XML 并删除具有相同“FULFILMENT_LINE_ID”值的冗余记录，同时删除“ORIG_SYS_PARENT_INSTANCE_REF”、“[=28=” ]”为冗余节点
像下面这样输入XML

我已经在下面的编辑器中更新了我的输入和 xslt
https://xsltfiddle.liberty-development.net/bET2rXn/4
https://xsltfiddle.liberty-development.net/bET2rXn/5 做

可能会让你更接近，很难说，所有的命名空间，长元素名称和长数据是否已经是你想要的结果。我想在您的实际应用程序中，声明的所有命名空间都在别处使用。
如果您希望您的其他模板删除要应用的某些元素，您需要将您的节点推送到它们，例如<xsl:apply-templates select="if (current-group()[2]) then current-group()[2] else ." /> 会将单个项目组的第一个和单个项目以及多个项目组的第二个项目推送到您的模板。
我希望按原样复制输入 XML 并删除具有相同“FULFILMENT_LINE_ID”值的冗余记录，同时删除“ORIG_SYS_PARENT_INSTANCE_REF”、“[=28=” ]”为冗余节点

可能会让你更接近，很难说，所有的命名空间，长元素名称和长数据是否已经是你想要的结果。我想在您的实际应用程序中，声明的所有命名空间都在别处使用。
如果您希望您的其他模板删除要应用的某些元素，您需要将您的节点推送到它们，例如<xsl:apply-templates select="if (current-group()[2]) then current-group()[2] else ." /> 会将单个项目组的第一个和单个项目以及多个项目组的第二个项目推送到您的模板。
