enriching payload

[pedrodantas]

Hi guys,

I'm calling a target endpoint from which I get some XML data in a format similar to the one below:

PAYLOAD 1:

<rooms>
	<room>
		<id>1</id>
		<name>...</name>
	</room>
	<room>
		<id>1</id>
		<name>...</name>
	</room>
	...
	<room>
		<id>N</id>
		<name>...</name>
	</room>
</rooms>

Then I do a callout from which I get some JSON data:

PAYLOAD 2

{
	{
		"id": 1, 
		"type": XXXXX
	},
	{
		"id": 2,
		"type": XXXXX
	},
	...
	{
		"id": N,
		"type": XXXXX
	}
}

The id's from payloads 1 and 2 are correlated. What I want is to enrich the payload 1 with the "type" element from payload 2, so that in the end I return a JSON in the format:

DESIRED FINAL PAYLOAD:

{
	"rooms": {
		"room": [
			{
				"id": 1, 
				"name": XXXXX
				"type": XXXXX
			},
			{
				"id": 2,
				"name": XXXXX
				"type": XXXXX
			},
			...
			{
				"id": N,
				"name": XXXXX
				"type": XXXXX
			}
		]
	}
}

I know translating from XML to Json is trivial, but I'm not sure which policy I should use to enrich the payload. I thought transforming payload 2 to XML, then use a XSL policy to enrich the XML, then finally transform everything to JSON again. But it seemed a rather clunky solution, and I'm not even sure if that's possible with XSL (I don't have much experience with XSL).

So, any suggestions on the best approach here? Will I have to do it all manually with javascript?

Thanks!
