How do I test a variable to see whether it contains a node, or something
else (usually, in the case I'm working on, an empty string)? Everything I
try causes an error if the variable contains a string. I have some code
that will only work on nodes, and before calling this code I need to test
and do something different if the variable doesn't contain a node.
