It is not so hard! :-)

You can read the file line-by-line and check each line if your keyword, a colon and a number are contained. This can be done by a pattern-matching using a regex. The tricky thing is to find a siutable regex. In your case I would start with:

/Input\s+:\s+(\d+)/;

If you have your line in a variable called $line, you could write 
if ($line =~ /Input\s+:\s+(\d+)/) { print $1," is the value of Input";
+ }
