I am trying to transform an xml based on groupBy in dataweave, however I also need to remove few json attributes from output.
Input json:
[ {
"m": {
"a": "a",
"b": "b"
},
"tag1": "A",
"tag2": "v1",
"tag3": "v1" }, {
"m": {
"a": "a",
"b": "b"
},
"tag1": "A",
"tag2": "v2",
"tag3": "v2" }, {
"m": {
"a": "a",
"b": "b"
},
"tag1": "C",
"tag2": "v3",
"tag3": "v3" } ]
Output json
**{
"A": [
{
"tag2": "v1",
"tag3": "v1"
},
{
"tag2": "v2",
"tag3": "v2"
}
],
"C": {
"tag2": "v3",
"tag3": "v3"
}
}**
I have tried following transformation (Mule 3.9) however the could not remove the extra attributes in json.
payload groupBy (item) -> item.tag1
Appreciate any suggestion on this and possibly explain how this can be achieved.
