How to create a collection that maps to this complex XML?

How To
1

I have to fill this XML structure with answers from a form:

<map_raggi>
	<map_raggio>
		<indirizzo>
			<![CDATA[ Viale matteotti, Firenze ]]>
		</indirizzo>
		<latitudine>43,78812</latitudine>
		<longitudine>11,24871</longitudine>
		<raggio>1</raggio>
	</map_raggio>
	<map_raggio>
		<indirizzo>
			<![CDATA[ Viale dei Mille, Firenze ]]>
		</indirizzo>
		<latitudine>43,7870808</latitudine>
		<longitudine>11,269691899999998</longitudine>
		<raggio>0.5</raggio>
	</map_raggio>
</map_raggi>

There can be 1 to 3 map_raggio elements.
I can’t use an if within the Create XML module.
So, I was thinking to build a collection that correctly maps to the XML and map the connection to the map_raggio element.

I’ve done it for another node, but it has a much simpler structure.

This is the data structure I’m using to create the XML

Does it mean I have to create an array containing 4 key-value pairs, for indirizzo, latitudine, logitudine, raggio?
