Hi Robert,
Not sure what you want to do after opening but I have some code that
extracts a time range out of a date tree. Maybe you can reuse the
searching parts ...
Cheers,
Martin

(defun mp26/org-find-headline-prefix-in-buffer (heading &optional buffer pos-only)
"Find node with heading-prefix HEADING in BUFFER.
Return a marker to the heading if it was found, or nil if not.
If POS-ONLY is set, return just the position instead of a marker.
The heading prefix must match as prefix of the full headline. It
may have a TODO keyword, a priority cookie and tags in the
standard locations."
