What should the key-value pairs be? Is 's' included? I'm assuming that you want something like this:

%a1 = (
   'Name'=>'sandy',
   'sport'=>'cricket',
);

Is that basically what your goal is? Is there significance to the 's' characters in the string? Once it's known what you're looking for, one of the saintly regular expression masters here (sadly I'm still a greenhorn) could probably make quick work of it.

I should also ask, is that just a sample of data, or will it always be in exactly that format?
