Rails - Jan 2009 - Total Count Using "eval" in a single raw

Hi,

Can anyone help me to get the "namecount" using eval, see the data
belows;

>> namecount =
eval('':name=>{1=>{1=>{"first_name"=>"leon",
"last_name"=>"may"},
2=>{"first_name"=>"lion",
"last_name"=>"king"}}}'')

I want an output should be "namecount = 2", because I''m
counting how
many "name" in one raw (1record).



Thanks in Advance!
