我正在将 XMl 以上映射到 CSV 管道去限制的有孔，需要有关如何循环行项目注释并检查 NoteType 和 NoteCode 并打印注释文本值的帮助。

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

我的数据编织到 CSV 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)

})

我需要映射column_56。

Answer 1

这是让你获得评论文本的映射，我不确定你要问什么。

%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 ""
})
