Thank you very much, Robert!! Yes, now i have number (fixnum)
I have also problem, i try to add this value to array element :
convert_loadDOM = self.loadDOMstat
    n1 = convert_loadDOM[/Loading DOM finished: (\d+) ms/, 1]
    files_load_DOM[i]= files_load_DOM[i] + Integer(n1) 

    and i have error:
     undefined method `+' for nil:NilClass (NoMethodError)
