Though, I believe you can do exactly what you want and even base it on the
&filetype of the current buffer by writing your own expression map.
The YankRing plugin (http://www.vim.org/scripts/script.php?script_id=1234)
makes lots of use of the expression maps, which call a function to capture
changed text (for later reference).
These maps (the Vim standard key strokes) end up triggering a YankRing
function to do the heavy lifting.
In this case, the heavy listing is your rules based on &filetype and what
the current character is (move to the closing ], skip ','s inside of "" and
so on.
If you are interested, you can look up expression maps.
:h :omap
:omap <expr> da, YourFunction(',')
Or something along those lines.
HTH,
