No, it most likely won't.  Partly because there is a syntax error
right in the first line of the code.  You also mix "Value" and
"#{Value}" which are two totally different things.

You would need to tell us what values you have there in the Hash - if
it is a Hash at all.

Did you mean "if result has _keys_ like 'Value-8'"?  Because you use
"Value" as key above.

Frankly, I am not entirely sure what you are after.  If you want to
select based on keys in the Hash you could do:

result.select {|k,v| /\AValue-\d+\z/ =~ k}

Kind regards
