Hi, I'm trying to use templates in order to write more modulare code.

My question is: is possible to have a template returning an xml element, or at least more than just one variable?

I tried to use the copy-of statement but it doesn't seem to work properly.

As an example I paste here the code of my template;

template print-mcast-route($ip-address) {
	var $rpc = <get-multicast-route-information>{<extensive>;}
	var $results = jcs:invoke($rpc);
	
	for-each($results/route-family/multicast-route[multicast-group-address == $ip-address])
	{
	var $multicast-source-address = multicast-source-address;
	var $multicast-source-prefix-length = multicast-source-prefix-length;
	var $multicast-source = $multicast-source-address _ "/" _ $multicast-source-prefix-length;
	var $multicast-route-state = multicast-route-state;
        }

        copy-of $multicast-source;
        copy-of $multicast-route-state;
}

If I call this template, it returns only the $multicast-route-state, but not the $multicast-source variable.

I dont' think I am using the correct syntax, and I already tried several workarounds without any success....The documentation about templates did not help me so much (I studied the day-One books as well as the "configuration and diagnostic automation guide").

Thanks in advance for your help,

Try this in the template instead of copy-of:

<source> $multicast-source;

<route-state> $multicast-route-state;

Then, when you call the template, make sure you use the := conversion operator rather than just the = assignment operator:

var $results := { call print-mcast-route( $ip-address ); }

That way you can reference the values like this:

$results/source

or

$results/route-state

Thank you very much Curtis, I had already tried the syntax you suggest me but without using the conversion operator... 

Now it works perfectly
