For Loop 数据编织 mulesoft 问题

Question

我是 mulesoft 的新手，并且编写了用于遍历订单项（xml 中的产品线项）的 dataweave。但是，它不起作用，它只插入一个订单行项目，（订单行项目-product-lineitem）有什么指点吗？

输入

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<order xmlns="http://www.demandware.com/xml/impex/order/2006-10-31" order-no="00001101">
    <order-date>2020-07-09T12:55:28.663Z</order-date>
    <original-order-no>00001101</original-order-no>
    <product-lineitems>
        <product-lineitem>
            <product-id>65754</product-id>
        </product-lineitem>
        <product-lineitem>
            <product-id>65755</product-id>
        </product-lineitem>
    </product-lineitems>
</order>

您需要为多值节点添加 * 即 product-lineitem 然后您可以在输出中获得两个值。此处有更多详细信息：https://docs.mulesoft.com/mule-runtime/4.3/dataweave-selectors
