This is (a part of) my xml:

 <entname>
  <field1>AM</field1>
  <field2>Totaal</field2>
 </entname>
 <entname>
  <field1>FER</field1>
  <field2>Totaal</field2>
 </entname>

xmlToStruct gives: 
[entname]
    [$tags]
      [xmlClass] = element
    [field1] = "AM"
      [$tags]
        [xmlClass] = element
    [field2] = "Totaal"
      [$tags]
        [xmlClass] = element
[entname]
    [$tags]
      [xmlClass] = element
    [field1] = "FER"
      [$tags]
        [xmlClass] = element
    [field2] = "Totaal"
      [$tags]
        [xmlClass] = element

StructToJson gives:
       [entname]
          [field1] = "AM"
          [field2] = "Totaal"
        [entname]
          [field1] = "FER"
          [field2] = "Totaal"

Result should be:
            "entname": [
               {
                  "field1": "AM",
                  "field2": "Totaal",
               },
               {
                  "field1": "FER",
                  "field2": "Totaal",
               }
            ]

Converting this json to Struct gives (so the struct should be):
       [entname]
          [$tags]
            [jsonClass] = array
          []
            [$tags]
              [jsonClass] = object
            [field1] = "AM"
              [$tags]
                [jsonDataType] = string
            [field2] = "Totaal"
              [$tags]
                [jsonDataType] = string
          []
            [$tags]
              [jsonClass] = object
            [field1] = "FER"
              [$tags]
                [jsonDataType] = string
            [field2] = "Totaal"
              [$tags]
                [jsonDataType] = string

How can I add the required tags converting the xml to  the struct?
