如何在 mule 4 中用 0 替换“#N/A”

Question

我正在尝试将 xml 的所有属性中的 "#N/A" 值替换为 0。

输入xml:

<DTOSteps>
    <DTOStep Order="1" Name="Rated Premium" Operation="=" Factor="#N/A" Value="#N/A">
        <DTOSteps>
            <DTOStep Order="1" Name="Property Damage" Operation="=" Factor="#N/A" Value="#N/A">
                <DTOSteps>
                    <DTOStep Order="1" Name="AOI" Operation="=" Factor="#N/A" Value="#N/A"/>
                    <DTOStep Order="2" Name="Base" Operation="-" Factor="#N/A" Value="#N/A"/>
                    <DTOStep Order="3" Name="Deductible" Operation="-" Factor="#N/A" Value="#N/A"/>
                </DTOSteps>
            </DTOStep>
            <DTOStep Order="2" Name="Business Income And Extra Expense" Operation="+" Factor="#N/A" Value="#N/A">
                <DTOSteps>
                    <DTOStep Order="4" Name="AOI" Operation="=" Factor="#N/A" Value="#N/A"/>
                    <DTOStep Order="5" Name="Base" Operation="-" Factor="#N/A" Value="#N/A"/>
                    <DTOStep Order="6" Name="Deductible" Operation="-" Factor="#N/A" Value="#N/A"/>
                </DTOSteps>
            </DTOStep>
        </DTOSteps>
    </DTOStep>
    <DTOStep Order="2" Name="Term Factor" Operation="X" Factor="#N/A" Value="#N/A"/>
</DTOSteps>

关于如何在 dataweave 2.0 中替换有什么想法吗？

Answer 1

使用下面给出的脚本。

%dw 2.0
output application/xml
var updateAttribute = (element) ->
  element mapObject (value, key) -> {
    (key) @(
        (
          if (key.@?)
            (key.@ mapObject ((attr_value, attr_key) -> { 
                    (attr_key): if (attr_value == "#N/A") "0" else attr_value
                }))
          else {}
        )
    ) :
    if (value is Object)
      updateAttribute(value)
    else value
  }
---
updateAttribute(payload)
