Generate array of specified xml element

[harlequin]

Describe the bug
I want to generate always an array of a specific xml element in json output

Version of yq: 4.273

Input XML

<root>
    <item>
        <child>1</child>
    </item>
    <item>
        <child>1</child>
        <child>2</child>
        <child>3</child>
    </item>
</root>

Command
The command you ran:
C:/oc/yq -p=x -o=j test.xml

Actual behavior

{
  "root": {
    "item": [
      {
        "child": "1"
      },
      {
        "child": [
          "1",
          "2",
          "3"
        ]
      }
    ]
  }
}

Expected behavior

{
  "root": {
    "item": [
      {
        "child": [
           "1"
        ]
      },
      {
        "child": [
          "1",
          "2",
          "3"
        ]
      }
    ]
  }
}

Is this possible?

Yes, you can do it like this:

yq '(.root.item[].child | select(tag != "!!seq")) |= [.]' test.xml -p=x -o=j

Explanation:

• We want every .root.item[].child to be a sequence, so find all the ones that aren't a sequence (.root.item[].child | select(tag != "!!seq"))
• And wrap their value in an array |= [.]
