我的代码看起来像这样

%dw 2.0
output application/csv header = false , separator = "|" , quoteValues = false
---
payload.tXML.Message.*DistributionOrder map ((DistributionOrder , indexofDistributionOrder) ->  {
    column_1: "000000001",
    column_2: "0",
    column_3: "0",
    column_4: (LineItem.LineProcessInfo.LineRefTextField2 splitBy "_")[0] replace "[" with "" default "",
    column_5: (LineItem.LineProcessInfo.LineRefTextField2 splitBy "_")[1] replace "[" with "" default "",
    column_6: ????
    column_7: "",
    column_8: "",
    column_9: "",
    column_10: "",
})

因此，在上面的代码中，我循环每个行项以获取字段，但是在每个行项中，我必须为每个注释循环，并且对于每个注释，我需要将它放在不同的行中。例如，输出应如下所示，如您在示例中所见，如果行项目 2 有 3 个评论部分，我有 3 行 3 个评论。

您可以尝试在地图中执行地图。但是，如果您希望将结果对象写为 csv，则需要将其展平，因为它将导致数组中的数组。

请参阅下面的示例代码：

%dw 2.0
output application/csv header = false , separator = "|" , quoteValues = false

var payload = read("<tXML>
      <Header>

flatten(payload.tXML.Message.DistributionOrder.*LineItem map (LineItem) -> 
    LineItem.*Comment map (Comment) ->
    {
        column_1: "000000001", 
        column_2: "0", 
        column_3: "0", 
        column_4: (LineItem.LineProcessInfo.LineRefTextField2 splitBy "_")[0] replace "[" with "" default "", 
        column_5: (LineItem.LineProcessInfo.LineRefTextField2 splitBy "_")[1] replace "[" with "" default "", 
        column_6: Comment.CommentText, 
        column_7: "", 
        column_8: "", 
        column_9: "", 
        column_10: ""
    })

这将导致
