One more question: how do I map only the entries that has a specific property
defined? The following code didn't work.

(org-map-entries
(lambda () (...))
"mytag+myproperty<>nil")

Thanks,

Thank you very much Nick.

(info "(org) Using the mapping API") was the first doc I read which has very little information on how to use the "match" parameter. (info "(org) Matching tags and properties") does have a lot more detail though.
