我在 XMl 上方映射到 CSV 管道分隔格式，需要有关如何循环 LineItem-Comment 以及检查 NoteType 和 NoteCode 以及打印 CommentText 值的帮助。

这是我的条件

Loop Over  /tXML/Message/DistributionOrder/LineItem/Comment 
If
/tXML/Message/DistributionOrder/LineItem/Comment/NoteType = SC and /tXML/Message/DistributionOrder/LineItem/Comment/NoteCode = 02
Then
Remove start and end index of /tXML/Message/DistributionOrder/LineItem/Comment/CommentText

我的 csv 数据编织看起来像这样

%dw 2.0
output application/csv header = false , separator = "|" , quoteValues = false
---
payload.tXML.Message.DistributionOrder.*LineItem map ((LineItem , indexofLineItem) ->  {

column_1: "000000002",
    column_2: (payload.tXML.Message.DistributionOrder.ProcessInfo.RefTextField8 splitBy "_")[0] replace "[" with "",
    column_3: if(payload.tXML.Message.DistributionOrder.ProcessInfo.RefNumberField1 != null) (payload.tXML.Message.DistributionOrder.ProcessInfo.RefNumberField1) else "00000000",
    column_4:"",
    column_5:"",
    column_6: "",
    column_7: "",
    column_8: "",
    .
    .
    .
    .
    .
    .
    coulmn_56: ?(
    If
/tXML/Message/DistributionOrder/LineItem/Comment/NoteType = SC and /tXML/Message/DistributionOrder/LineItem/Comment/NoteCode = 02
Then
Remove start and end index of /tXML/Message/DistributionOrder/LineItem/Comment/CommentText)



})

我需要为 column_56 映射。

Answer 1

这是获取commentText的映射，我不确定你要的是什么。

%dw 2.0
output application/csv header = false , separator = "|" , quoteValues = false
---
payload.tXML.Message.DistributionOrder.*LineItem map ((LineItem , indexofLineItem) -> {
    column_1: "000000002",
    column_56: (LineItem.*Comment[?($.NoteType == 'SC' and $.NoteCode == '02')][0].CommentText) replace "[" with "" replace "]" with ""
})
