Am a novice in programming.
Have created a flow in Pipedream, where i converted an xml object to json.
Need to get all values 'name' with format 123456-123-1234 as from a certain level (see picture). The issue is that some levels contain the item straight away, some have multiple items, and therefore another nested array.
The full json array =

My Code in a NodJs Step in pipedream:
export default defineComponent({
async run({ steps, $ }) {
// let recordb = (steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[1].items.item.length)
for (let i = 0; i < steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item.length; i ) {
let record = (steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[i].items.item)
if (record !== undefined){
console.log(record);
}//if1
let lth = steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[i].items.item.length;
if (lth !== undefined){
//console.log(steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[i].items.item.length);
for (let j = 0; j < steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[i].items.item.length; i ) {
let recordb = (steps.xml_to_json.$return_value.resource.attributes.attribute[4].items.item.items.item[i].items.item[j])
if (recordb !== undefined){
console.log(recordb);
}//if2
}//for2
}
}//for1
//console.log(recordb);
},
})
The output:

Does something like this work?
Basically, check if the item is an Array or not and either loop over it if it is or else grab the name property.
