如何使用 Dataweave 2.0 从有效载荷中获取数组中的值对象

Question

我正在尝试将 XML 输入负载转换为 JSON 格式。有人可以帮助我使用 Dataweave 吗？

提前致谢

这是您要输出的内容吗？

输入

<root>
    <entry>
        <ID>ABS</ID>
        <DEPARTMENT>EDF</DEPARTMENT>
        <NUMBER>1234</NUMBER>
        <YEAR>2021</YEAR>
        <POSITION1>12</POSITION1>
        <POSITION2>13</POSITION2>
    </entry>
    <entry>
        <ID>ABFG</ID>
        <DEPARTMENT>123ER</DEPARTMENT>
        <NUMBER>4544</NUMBER>
        <YEAR>2022</YEAR>
        <POSITION1>20</POSITION1>
    </entry>
</root>

脚本

%dw 2.0
output application/json

fun returnPosition(pkey,position) = {
    b:(payload.root.*entry[position] - "ID" - "DEPARTMENT" - "NUMBER" - "YEAR")
}
---
root:{
    entry: flatten(payload.root.*entry map (entryValue,entryIndex) -> {
    a: flatten(1 to sizeOf((entryValue) - "ID" - "DEPARTMENT" - "NUMBER" - "YEAR" ) map {
                "ID": entryValue.ID,
                "DEPT": entryValue.DEPARTMENT,
                "NUMBER": entryValue.NUMBER,
                "YEAR": entryValue.YEAR ++ returnPosition("POSITION"++($$+1),(entryIndex)).b[($$)]

                

    })
}.a)
}

输出

{
  "root": {
    "entry": [
      {
        "ID": "ABS",
        "DEPT": "EDF",
        "NUMBER": "1234",
        "YEAR": "202112"
      },
      {
        "ID": "ABS",
        "DEPT": "EDF",
        "NUMBER": "1234",
        "YEAR": "202113"
      },
      {
        "ID": "ABFG",
        "DEPT": "123ER",
        "NUMBER": "4544",
        "YEAR": "202220"
      }
    ]
  }
}
