Hi there

Is there a function that will give me the content of the current item? I
mean simply the text of the whole item without its heading or properties
drawer.

It seems to me likely that such a function would exist, but I haven't been
able to find it in the documentation.

Many thanks
Richard

I don't know of a function. Something like this may be what you want.
not all elements have :contents-begin though

(let ((el (org-element-context)))
 (buffer-substring-no-properties
 (org-element-property :contents-begin el)
 (org-element-property :contents-end el)))


It also a little tricky to figure out what to do about subheadings. Do
they count as content or not?

I think this is basically what you are looking for.

(defun org-heading-content ()
  (interactive)
  (let (bp ep)
    (setq bp (save-excursion
	       (or (and (outline-previous-heading)
			(progn (org-end-of-meta-data)
			       (point)))
		   (point-min)))
	  ep (save-excursion
	       (or (and (outline-next-heading) (point))
		   (point-max))))
    (buffer-substring-no-properties bp ep)))

That is very kind of you - many thanks indeed for your assistance.
