You had 
my $NewRev = "\tabc\tkis17.1.33en_12345.exe<h href";
my $RedirectUrl;
## and then... for($NewRev = $RedirectUrl);

That assigns $RedirectUrl to $NewRev and then uses that result in the for loop. Since $RedirectUrl is null undefined (the simple my $RedirectUrl; statement). That is the source of one of your "use of uninitiatized value warnings". Note that the code keeps going after a warning. A warning is not considered "fatal". An "error" will stop the program.

Make Sense?

Update: I don't want to quibble about definitions of definitions of "warning, syntax error" or whatever. You have some code that runs now without any warnings. Continue on with your experimentation...I commend you for that effort.
