How to handle NULL Objects

Hey there,
how can i handle NULL Objects in Fin250?
I get runtime errors whenever i try to assign an Empty-Object to an other Object.
For example (msxml-Automation):
ReturnedNodeList := RootNode.selectNodes(NodePath);
If RootNode.selectNodes(NodePath) returns the NULL-Object, i get an error message.
Any ideas?
How can i simulate the ISCLEAR-function from attain?
thanks in advance

I tried something like :
IF RootNode.selectNodes(NodePath).nodeName <> '' THEN ...
But it doesn't work. I'm getting an error message that the object is not instantiatet.
