Then I presume you want a transformation something like:

magic("ABC\\Name X\\Gender")
=> [["Name", "ABC"], ["Gender", "X"]]
or
=> { "Name" => "ABC", "Gender" => "X" }

You can then manipulate the alist or hash (key-value pairs) as you  
wish.  (for the alist, "association list", you can use the Array#assoc  
method)

Depending on where whitespace is permitted in the original string, you  
might be able to:

irb> "ABC\\Name X\\Gender".split(' ').map{|pair| pair.split(/\ 
\/).reverse }
=> [["Name", "ABC"], ["Gender", "X"]]
