Subject: Re: Using a Regexp to find a Hash Key?


Actually, that was very good advice, THANK YOU!
I did not even consider using an Enumerable method, I was stuck on  
Hash methods.

if foo_key = hash.find { |k,v| k =~ /^foo_(\d+)$/ }[0]
   # Now I can use foo_key to look at the values
   # I can also use $1 where needed for the match
end


  Thanks again,
  Ken
