Can property of object in array be deleted using change node?

[mfeb]

If so, what would be the path to the elements in the array?

Here's a snippet of the structure, and I'd like to remove the property "xml:lang": "en"

{
  "team": ":Cleveland_Cavaliers",
  "results": {
    "head": {
      "vars": [
        "Player",
        "Label"
      ]
    },
    "results": {
      "bindings": [
        {
          "Player": {
            "type": "uri",
            "value": "http://dbpedia.org/resource/Matthew_Dellavedova"
          },
          "Label": {
            "type": "literal",
            "xml:lang": "en",
            "value": "Matthew Dellavedova"
          }
       },

No it can't, it isn't that sophisticated.
But we should look at how we could support that... something like jsonpath (equivalent to Xpath) would be needed.

Does, https://github.com/kmi/node-red-contrib-jsonpath help ?

[mfeb]

Well, I did go there next. I think I can get to the property using JSONPath but I couldn't figure out how that could be used to remove all instances of a given property.

[Dave C-J]

Sounds like a custom function is required then...

[mfeb]

My next next step will be jsonpath-transform...if I can figure out how.

Thanks,

Mark

I maybe being a bit slow but if you pass the json into a function node, the resulting msg variable will be just a javascript object so you can use delete on it to delete the element. If you are likely to have multiple elements which I think you are, all you need is a loop around the bit of the object you need to look in with an appropriate delete inside the loop.
