How-to access org-mode data

[Torsten Wagner <torsten.wagner@gmail.com>]

Hi,

I try to extract certain information which are processed by org-mode.
As an example the compiled agenda-list. Basically, I want to have 
certain parts of the agenda in a variable (or an array) instead of a 
buffer.

I tried to follow org-agenda.el but this seems to be hard of a elisp 
beginner.
At the moment I'm unsure what would be the best way to get those infos.
I could run e.g.,
(org-agenda list nil nil 1)
however, this always end up in a buffer, which I could start parsing and 
closing afterwards, but maybe there is a more smart way? I don't want to 
break any code and try to get this on top of the original org-mode code.

To keep it simple for an example:
Create org-agenda get the very next thing which need to be done as a 
string into a variable call result

Any feedback is welcome

Thanks

Torsten
