2012-12-11 08:45:00.0 222.2
2012-12-11 08:46:00.0 111.3

2012-12-11 08:51:00.0 239.4
2012-12-11 08:52:00.0 376.4
2012-12-11 08:53:00.0 -9999.9

and you know the url of the website.

Is it possible to use javascript (or what should be used) to select the most recent timestamp
(but not the timestamp with the content -9999.9) and its value, and save the timestamp and the value
in two variables that can be displayed on another webpage?

There will be a new updates every minute that should
be streamed to the other page.
