如何在 Mule Data weave 2.0 中进行 XML 转换

问题描述

我有两个来自 DB 的结果集，一个在 Payload 中，另一个在另一个变量中。我正在尝试遍历多个结果集以形成 xml。在第二次迭代期间，我需要从第二个结果集中获取多个实体标签。

有效载荷：

[
    {
        "Version": "1.0","ID": "VKP","Password": "VKP","Username": "VKP","id": "123456789","Amount": "1000","StreetAddress": "Oaks Ave"
    }
]

vars.borrowerResult：

[
    {
        "firstname": "Vinoy","lastname" :"VKP"
    },{
        "firstname": "Kevin","lastname" :"Peter"
    }
]

当前代码：

%dw 2.0
output application/xml
fun StreetAddressSizeCheck(data) = if(data != null and sizeOf(data) > 30) data[0 to 29] else data
---
DRIVERequest @(version : "1.00") : {
    Authentication @(ID : "*****",Password : "******",Username : "******") : null,BatchRequest : payload map {
        Mortgage @(id : $.id,Amount : $.Amount) : {
            Property @(StreetAddress : StreetAddressSizeCheck($.StreetAddress)) : null,//Below is the place i am trying to add the code to iterate over variabe.
            // If there are multiple objects i need to get as much entries are there in Array.
            vars.borrowerResult map{
                Borrower @(firstname :$.firstname,lastname : $.lastname) : null,}
    }
}

预期的 XML 输出为

<?xml version='1.0' encoding='UTF-8'?>
<DRIVERequest version="1.00">
  <Authentication ID="*****" Password="******" Username="******"/>
  <BatchRequest>
    <Mortgage id="123456789" Amount="1000">
      <Property StreetAddress="Oaks Ave"/>
      <Borrower firstname="Vinoy" lastname="VKP"/>
      <Borrower firstname="Kevin" lastname="Peter"/>
    </Mortgage>
  </BatchRequest>
</DRIVERequest>

解决方法

编辑：啊..萨利姆发布了相同的答案。应该刷新页面 :) 我正忙着清理格式啊。

output application/xml
fun StreetAddressSizeCheck(data) = if(data != null and sizeOf(data) > 30) data[0 to 29] else data
---
DRIVERequest @(version : "1.00") : {
    Authentication @(ID : "*****",Password : "******",Username : "******") : null,BatchRequest : payload map {
        Mortgage @(id : $.id,Amount : $.Amount) : {
            Property @(StreetAddress : StreetAddressSizeCheck($.StreetAddress)) : null,(vars.borrowerResult map {
                Borrower @(firstname :$.firstname,lastname : $.lastname) : null,})
        }
    }
}

地图周围的括号是必要的，因为它们基本上代表“将其扩展到父对象中”。如果没有它们，您需要为要分配给的数组设置一个键。

试试这个：

%dw 2.0
output application/xml
//2nd Result set in Variable 
var borrowerResult= [
{
    "firstname": "Vinoy","lastname" :"VKP"
},{
    "firstname": "Kevin","lastname" :"Peter"
}
]

fun StreetAddressSizeCheck(data) = if(data != null and sizeOf(data) > 30) data[0 to 29] else data
---
DRIVERequest @(version : "1.00") : {
Authentication @(ID : "*****",BatchRequest : payload map {
Mortgage @(id : $.id,Amount : $.Amount) : {
  Property @(StreetAddress : StreetAddressSizeCheck($.StreetAddress)) : null,(borrowerResult map{
             Borrower @(firstname :$.firstname,})

 }
 }
}
