_call function -> using output

escape

Hi

if i use _call((_image(51)).onmouseover) using the [start-->] button I get some output in the grey box bellow,
how can I access this output, means I want to store it in a variable as a string (want to use assertEqual later)

$mouseovertext = _call((_image($id)).onmouseover); doesn't work .

regards

escape

Have found a different solution to check this, but all in all it would be nice to know how you can use this output - a suggestion extend the API with a function _debugToVar .... so logging and debugging will be more variable .....
