搜索 XML 属性并将其分组

Question

我需要搜索一个 XML 属性值，将其分组并形成相应的 JSON 元素。

现在举例：Label 是我的 AttributeID，我有 2 个属性 Label。（实时 - 可以是 'n' 次。）需要将 2 个标签分组为单个 JSON 元素。

VendorClass、VendorDivision 和 VendorDept 都应包含在 Vendor Json 属性中。 VendorClass attributeValue 应映射到 Vendor 内的 classCode，其他 2 个代码应为 null。同样，VendorDept attributeValue 应映射到 DeptCode。VedorDivision 属性值映射到 DivisionCode。

O/PJSON（映射）： type - 应该总是大写字母 - 映射到 attributeID，名称 - 小写字母 - 映射到“attributeId_attributeValue”， id/code - 是 attribute_value

下面是我的i/pXML

<CurrentRule Currency="USD"
    CurrentStatus="ACTIVE"
    Priority="0"
    RuleCategory="Current"
    RuleType="COMBINATION"
    >
    <CurrentRuleTargetAttributeValueList/>
    <CurrentRuleAttributeValueList>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="Label"
            TriggerAttributeValue="10"/>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="Label"
            TriggerAttributeValue="1003"/>
        <CurrentRuleAttributeValue 
        TriggerAttributeID="ABCDCode"
            TriggerAttributeValue="AC"/>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="ABCDCode"
            TriggerAttributeValue="FD"/>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="VendorClass"
            TriggerAttributeValue="00N"/>
        <CurrentRuleAttributeValue
            TriggerAttributeID="VendorDept"
            TriggerAttributeValue="100"/>
        <CurrentRuleAttributeValue
            TriggerAttributeID="VendorDivision"
            TriggerAttributeValue="10"/>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="VendorMarket"
            TriggerAttributeValue="QVC"/>
        <CurrentRuleAttributeValue
            TriggerAttributeID="PriceCode"
            TriggerAttributeValue="FP"/>
        <CurrentRuleAttributeValue 
            TriggerAttributeID="ProductNumber"
            TriggerAttributeValue="A0000"/>
        <CurrentRuleAttributeValue
            TriggerAttributeID="Trader"
            TriggerAttributeValue="1010"/>
        <CurrentRuleAttributeValue
            TriggerAttributeID="Trader"
            TriggerAttributeValue="1046"/>
    </CurrentRuleAttributeValueList>
</CurrentRule>

根据描述的规则，这是最佳近似值。我将留给您如何确定它是 id 还是 code 以及未明确解释的其余输出。

%dw 2.0
output application/json
---
{
    header: {
        "type": "ORDER",
        "name": "merch-attribute-example",
        "createUser": "admin"
    },
    filters: payload.CurrentRule.CurrentRuleAttributeValueList 
        mapObject ((value, key, index) -> 
            {
                attr: key.@
            }
        ) 
        pluck (($$):$)
        groupBy ((item, index) -> item.attr.TriggerAttributeID)

        mapObject ((value1, key1, index1) -> 
            (key1): value1 map 
                {
                    "type": upper(key1), 
                    name: lower(key1) ++ "_" ++ $.attr.TriggerAttributeValue,
                    id: $.attr.TriggerAttributeValue
                }
        ) 

}

输出：
