Subject: Buffer positions from `org-element-map'?
Date: Tue, 27 Jan 2015 17:48:42 -0800	[thread overview]
Message-ID: <alpine.OSX.2.00.1501271726400.663@charles-berrys-macbook.local> (raw)


I'd like to be able to determine the buffer position of (say) inline
src blocks as in the following and operate on them using
`org-element-map'. This might enable modification and replacement of a
few objects in a large buffer.

What I would like is to have the same values of :begin as would be
obtained by placing the cursor on each inline src block and evaluating
(org-element-context). As is evident below, :begin is sometimes a
relative position.

Suggestions on how to get the buffer position or some other way to do
in situ buffer modifications from `org-element-map' without
interpreting a complete parse tree (which I expect requires more
computation that doing selected `delete then insert' operations) are
welcome.

Chuck
