Simple question re toggleNode.pl

Like many others (i'm sure) we have a simple need to toggle the state of a node just like the toggleNode.pl code example from the 4.x SDK did. Has that sample been ported? Does anyone have a code snippet that would give us a good head-start on this? This seems like a simple function that would make a good code sample!

 

 

Any help or pointers would be most appreciated!
