Extract data using javascript

Hi,

I have created a BW reportin BeX WAD. At viewtime (in internet explorer), I'm extracting some data from a table in the report with some custom javascript (I'm using HTML DOM).

Is there any way to directly query the data provider of the table (in javascript) to get the needed data? Because using DOM is not that elegant and not that easy to generalize (the number of rows varies depending on the number of characteristic values etc).

Thanks,

Jeroen
