騾子中的 dataweave 1.0 到 2.0 遷移

Question

嘗試將以下dataweave 從 1.0 轉換為 2.0 ，但我嘗試過的所有操作都會出現以下錯誤，例如

SkipNullon 顯示錯誤

不接受使用命名空間，

@PostalCode[0..4] 無效並且

無法使用參保PrimaryAddr 訪問參保信息中的值。

數據編織 1.0：

%dw 1.0
%output application/xml skipNullOn="everywhere"
%var insuredInfo = payload.DTOApplication.DTOInsured
%var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
%namespace ns0 http://decisionresearch.com/RateMaker
---
ns0#rate:{
    ns0#code:insuredPrimaryAddr,
    ns0#ZipCode: payload..Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0].@PostalCode[0..4] default ""
}

我嘗試了 Dataweave 2.0：

%dw 2.0
output application/xml skipNullOn="everywhere"
var insuredInfo = payload.DTOApplication.DTOInsured
var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
namespace ns0 http://decisionresearch.com/RateMaker
---
ns0#rate:{
    ns0#code:insuredPrimaryAddr,
    ns0#ZipCode: payload..Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0].@PostalCode[0..4] default ""
}

關於如何在 dataweave 2.0 中編寫相同內容的任何想法？

Answer 1

在 dataweave 2.0 中，我們使用to運算符進行數組索引。

%dw 2.0
output application/xml skipNullOn="everywhere"
var insuredInfo = payload.DTOApplication.DTOInsured
var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
ns ns0 http://decisionresearch.com/RateMaker
---
ns0#rate:{
    ns0#code:insuredPrimaryAddr,
    ns0#ZipCode: payload..Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0].@PostalCode[0 to 4] default ""
}

Output

<?xml version='1.0' encoding='windows-1252'?>
<ns0:rate xmlns:ns0="http://decisionresearch.com/RateMaker">
  <ns0:ZipCode>80003</ns0:ZipCode>
</ns0:rate>
