Subject: Re: Ruby(and programming) beginners question regarding 'NoMethodError' while using Hpricot

Hi!
 I tried to find the class of the object on which I am using the method
next_sibling using the  code below is returning (by iterating it for 25
times )
>sheet1[num,1]=doc.search('td[text()="PE ratio"]').first
>puts num # num is |num|
>puts sheet1[num,1].class
It turns out it gives 'nil class' for 13th, 15th 16th and 24th
iteration.
So 'next_method' gives a no method error.

Please help me with this problem
