Exactly.

You mean that they do not start with the long "correct" prefix?
Or do you mean something else? (I thought a small example would
more readable, so that's why I'm using these fake OIDs.)

Yup.

Not sure I understand your modification. A leaf oid has no 
children, so to me it makes sense that findSymbolChild()
returns null. Could you send a snipplet from the MIB file
you're trying to parse? Just so that I can understand the
issue here. If don't want to disclose it to the world, 
please use my private email address.
