Get back data from Reports

I have just started working with RS 2005 and was wondering if / how I can do the following.

I created an asp.net website that has a report viewer to show my reports on the web.
In addition there is a page that lists all of the reports a user has access to, which is pretty much a series of links:

Report 1
Report 2
Report 3
.....

Now in my reports I generally create a grand total of one of the column and was wondering if there was some way to get that information back into an asp page, ie:

Report 1 - $125,713
Report 2 - ($23,111)
Report 3 - $1,762,142

I was thinking if there was some way to send a parameter to the report like Summary=True which would tell it to just return a XML bit of data holding the total for that report (Anything will work, doesn't have to be XML). So the page with the report links would call each of the reports.

I realize that it would probably be possible to do this through a stored procedure, but that would just create another point of maintenace. Instead I could create some function in all of my reports and have a standardized way of doing this so my webserver or database wouldnt have to be updated all the time.

Thanks, and let me know if there is any other information I can provide to make this clearer.

Try using the XML renderer. You will get a "report" which is really just an XML stream with the data. You can then XPath into it to get the values you are interested in.|||

Sounds promising. Being rather new to reports, are there any pages you can think of off hand that provide examples or explanations?
