I'm loading xml data from a remote server that refreshes
every few minutes with updated data from the same remote xml. If
the internet connection is lost, I want to continue to display the
previously downloaded data, but I can't figure this one out... When
I pull my internet plug, the app shows UNDEFINED when it goes
through the next loop - it's still trying to get the data, but I
need it to run function that will check the internet, ping an IP or
whatever and if that fails then don't get th enew data.
