            </Comment>
            </LineItem>
        </DistributionOrder>
      </Message>
    </tXML>

我在XMl上方映射到CSV管道定界的穿孔，并且需要有关如何循环LineItem-Comment以及检查NoteType和NoteCode以及打印CommentText值的帮助。

这是我的情况

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dataweave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。

技术

这是使您获得commentText的映射，我不确定您要什么。

%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 ""
})
