您可以使用子代数据选择器（使用..）从xml文档中检索所有BOMTable，因此无需递归浏览文档。然后使用map/flatMap输出必要的字段 请参阅以下资料：

请注意，输出仍然与您发布的预期输出不同，根据您在其中一条评论中发布的映射规则，我认为这是不正确的。请澄清输入中每个级别的id、productId和parentId的来源。输出似乎与给定的输入不正确相关。例如，项目96AR158位于RecId“111111111”下，但输出显示其位于“222222”下。如上所述，请澄清预期输出的映射规则。id与BOM内的RecId映射，productId映射到BOM中的ItemId，parentId是BOMTable的直接RecId的RecId。现在输入已更正。从查看：您有一个解决方案，如果有其他答案，您应该解释为什么您的答案与其他答案的工作方式不同。是的，它有问题，但您提供的概念足以解决该问题。非常感谢！！！
