[TYPO3] gmenu, splitchar, xy-offset

[Sebastian Fuchs]

Hello.

once again typo makes me feel like a complete idiot, because i couldnt 
make this typoscript if-statment work.
probably some TS guru can help?? :)

I have a nice graphical menu (GMENU) generated from the page title. Now 
when the page titles become too long I want to split the menu entries 
into two rows. using splitChar and the | as splitting character, which 
works fine. please, see the ts code below....
Now my problem is the height of the generated grafics.
what i would like to have is:

if there is a splitChar in the string set the XY - offset to double as
if there were no splitChar.

in other words:

if 20 is empty
then generate a grafic with XY = [10.w],[10.h] + [20.h] + 8
otherwise generate a grafic with XY =  [10.w],[10.h] + [20.h] + 16

I dont have any clue where and how to insert this if-statment, perhaps 
it can be solved differently.
every hint will be a great help.....
