Question

从下面的 XML 得到“0011x000014VegoAAC”的正确 Dataweave 表达式是什么？

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<order order-no="00000907" xmlns="http://www.demandware.com/xml/impex/order/2006-10-31">
    <order-date>2020-07-10T08:57:05.076Z</order-date>
    <current-order-no>00000907</current-order-no>
    <product-lineitems>
        <product-lineitem>
            <net-price>54.17</net-price>
        </product-lineitem>
    </product-lineitems>
    <custom-attributes>
        <custom-attribute attribute-id="Adyen_pspReference">852594371442812G</custom-attribute>
        <custom-attribute attribute-id="Adyen_value">7099</custom-attribute>
        <custom-attribute attribute-id="sscAccountid">0011x000014VegoAAC</custom-attribute>
    </custom-attributes>
</order>

Answer 1

自定义属性看起来像标准标记。将其包装到引号中，它将正常工作。 custom-attribute 是一个数组，在 DW 转换中用星号表示。从这个数组（第 19 行创建它）我们过滤所有属性（由 @ 字符表示）等于 sscAccountId 的项目。

结果是一个只有一个元素的数组。

%dw 2.0
var payload =read('<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<order order-no="00000907" xmlns="http://www.demandware.com/xml/impex/order/2006-10-31">
    <order-date>2020-07-10T08:57:05.076Z</order-date>
    <current-order-no>00000907</current-order-no>
    <product-lineitems>
        <product-lineitem>
            <net-price>54.17</net-price>
        </product-lineitem>
    </product-lineitems>
    <custom-attributes>
        <custom-attribute attribute-id="Adyen_pspReference">852594371442812G</custom-attribute>
        <custom-attribute attribute-id="Adyen_value">7099</custom-attribute>
        <custom-attribute attribute-id="sscAccountid">0011x000014VegoAAC</custom-attribute>
    </custom-attributes>
</order>','application/xml')
output application/json
---
(payload.order."custom-attributes".*"custom-attribute") 
 filter (item) -> (item.@"attribute-id" ~= "sscAccountid")
