Pass a node of XML to a function

1

Good monday to all my fellow coders

I have a config XML and I’d like to pass a node (and all it’s child nodes) to a function.

I’m trying

function myFunction(xml:Array)

and

function myFunction(xml:XMLList)

but I always get: Type Coercion failed: cannot convert XML@1cee3da1 element… bla bla bla

So… how can I pass a piece of xml to a function and then use that to do something?

Regards

Pier
