数据编织2.0中的xml转换

Question

在我的例子中，我有一个XML请求和预期响应负载。但我不知道如何使用Dataweave 2.0 进行转换

输入XMl:

<?xml version="1.0" encoding="UTF-8"?>
<DTOApplication id="Application-1660258480-1493174910" ApplicationNumber="AP-00006354" Version="3.10">
<QuestionReplies id="QuestionReplies-1553101003-1178947042">
<QuestionReply id="QuestionReply-859195405-1832325773" Name="1000" Value="NO" VisibleInd="Yes"/>
<QuestionReply id="QuestionReply-1656171536-493197768" Name="1000A" VisibleInd="No"/>
</QuestionReplies>
<DTORisk id="Risk-156119133-1700981150">
<DTOCoverage>
<DTOStep id="Step-Coverage-1713637162-341585712-Premium" Status="Cleared"/>
</DTOCoverage>
</DTORisk>
<DTORisk id="Risk-156119133-1700981151">
<DTOCoverage>
<DTOStep id="Step-Coverage-1713637162-341585713-Premium" Status="Cleared"/>
</DTOCoverage>
</DTORisk>
<DTOCoverage>
<DTOStep id="Step-Coverage-1713637162-341585713-Premium" Status="Cleared"/>
</DTOCoverage>
<DTOCoverage>
<DTOStep id="Step-Coverage-1713637162-341585713-Premium" Status="Cleared"/>
</DTOCoverage>
<DTOCoverage>
<DTOStep id="Step-Coverage-1713637162-341585713-Premium" Status="Cleared"/>
</DTOCoverage>
</DTOApplication>   

输出XML:

<?xml version="1.0" encoding="UTF-8"?>

注：

• 输入和输出有效负载之间的区别在于DTOStep节点的值应该更新
• DTOStep的属性值每次从500自动递增

Answer 1

我怀疑您试图将DTOStep元素分别封装到DTOSteps父元素中。这可以使用update((运算符来完成。根据需要转换每个子元素mapObject((非常有用，因为它还提供了索引。您可能需要针对其他输入对脚本进行微调。

%dw 2.0
output application/xml
var keys=["DTORisk", "DTOCoverage"]
var startingValue=499
fun createOutputElement(keyName, index)=keyName match {
case "DTOCoverage" -> { DTOCoverage: DTOSteps: DTOStep @(Order:1, Name:"Final Premiun", Factor: index + startingValue, Value: index + startingValue): null }
case "DTORisk" -> { DTORisk: DTOCoverage: DTOSteps: DTOStep @(Order:1, Name:"Final Premiun", Factor: index + startingValue, Value: index + startingValue): null }
else -> dw::Runtime::fail("Unexpected key")
}
---
payload update {
case risk at .DTOApplication ->
risk mapObject ((value, key, index) -> 
if (keys contains key as String ) createOutputElement(key as String, index) 
else (key):value
)
}

输出：
