Thanks! That was a perfect example.

No problem, this list is for answering any kinds of problems or
questions! I'm not around so often right now (due to absent
Internet connection at home), so please don't count on my
responses being quick or anything... :-(

I hope, however, that everyone on the list feels free to help
out from time to time if you have some time to spare. Thanks in
advance for any help answering questions, etc!

Now, over to the issue at hand:

Ok, this is untested code, so please don't be too frustrated
if it doesn't compile... ;-)

  // get "XYZ" symbol
  startSymbol = (MibValueSymbol) mib.getSymbol("XYZ");
  // get "XYZ" object identifier value, i.e. 1.2.3.4.5
  startOid = (ObjectIdentifierValue) startSymbol.getValue();
  // get 1.2.3 object identifier value
  endOid = startOid.getParent().getParent();
  // get 1.2.3 symbol
  endSymbol = endOid.getSymbol();
  // print 1.2.3 symbol
  System.out.println(endSymbol);

Basically, what you do is to traverse the tree of OIDs that
are linked across MIBs. Note, however, that the OIDs are only
linked if the MIBs have been loaded with the same MibLoader
instance (which is usually the case, but anyway good to know).

Hope this helps!

Cheers,
