Mule DataWeave Group by And Sum

-1

我正在做一些相当简单的事情，希望我只是想念一条简单的声明，我正在尝试做一个小组并完成总结，但似乎无法使DataWeave完成任务我。任何帮助将非常感激！Mule DataWeave Group by And Sum

我有下面的XML

<?xml version="1.0" encoding="UTF-8"?> 
<getRecordsResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
<getRecordsResult> 
     <company>0a6979a72ba5020092d4a5a667da15ac</company> 
     <u_billed_amount>504</u_billed_amount> 
</getRecordsResult> 
<getRecordsResult> 
     <company>548839a72ba5020092d4a5a667da15e0</company> 
     <u_billed_amount>29.17</u_billed_amount> 
</getRecordsResult> 
<getRecordsResult> 
     <company>0a6979a72ba5020092d4a5a667da15ac</company> 
     <u_billed_amount>33.75</u_billed_amount> 
</getRecordsResult>

而且在dataWeave表达如下 -

%dw 1.0 
%output application/xml 
%namespace ns0 http://www.service-now.com/u_incident_task 

--- 
results: {(
    payload.getRecordsResponse.*getRecordsResult groupBy $.company map  { 

    amtToBill: ($.u_billed_amount) 

    } 
)}

其产生期望的分组，但是我需要总结结算的金额。

<?xml version='1.0' encoding='UTF-8'?> 
<results> 
    <amtToBill> 
     <u_billed_amount>29.17</u_billed_amount> 
    </amtToBill> 
    <amtToBill> 
     <u_billed_amount>504</u_billed_amount> 
     <u_billed_amount>33.75</u_billed_amount> 
    </amtToBill> 
</results>

我需要的是以下

<?xml version='1.0' encoding='UTF-8'?> 
<results> 
    <amtToBill> 
     <u_billed_amount>29.17</u_billed_amount> 
    </amtToBill> 
    <amtToBill> 
     <u_billed_amount>537.75</u_billed_amount> 
    </amtToBill> 
</results>

我知道必须有在dataWeave求和，我还没有找到它。

我发现我自己的答案，只是这样做 -

amtToBill: sum $.u_billed_amount
