Capture ASP output for monitoring

How do I Capture ASP.NET output and then store it as temp memory so that I can use them in an application to do comparison.

example.

there's this site which has ASP output. Sorry I do not have server access, what I can do is view the output.

The site by the way is a monitor for all users logged in and in which ever channel.

output e.g.

Channel 1

Username              logged in (0 / 1)
Username 1                    1
John Smith    开发者_Go百科                1
George B                      0

Channel 2

Username              logged in (0 / 1)
Username 1                    1
John Smith                    0
George B                      0

what I wanted to do is to capture this output and then show them this way.

Username                    Channel 1             Channel 2            Total
Username 1                      1                     1                  2
John Smith                      1                     0                  1
George B                        0                     0                  0

I dont knw where to start.

A quick and dirty solution would be to screen-scrape the web page, load the data into an array, and sum on output.

Once you have chosen the platform you want to develop on, come back here and ask more specific questions as you run into issues.
