Re: tdom - not understanding "nextSibling"

[chedderslam]

This is part of a recursive call that is parsing out the document, so
I can't hard-code the reference like you did in your example.  Is
there a way to test if the current node has a sibling?  I understand I
can set a variable to [$doc nextSibling], but I assume because this is
an object I can't just check for length.  Would I somehow be able to
check if the [$doc nextSibling] command results in a null value, or
will it always result in an empty string if there is no sibling?

Sorry, I'm really new to this.  I appreciate the help.
