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

From: Estanislau Trepat <estanis@...>

Hi Sandeep.

The #search method returns an Hpricot::Elements object, which is somewaht
similar to an array. You should call #next_sibling on any of the elements
inside that collection, which, in fact, are Hpricot::Elem objects. For
instance:

# perform search
> elements = doc.search('td[text()="PE ratio"]')
=> #<Hpricot::Elements[{elem <td> "PE ratio" </td>}]>

# get the targeted cell
> cell = elements*.first.*next_sibling
=> {elem <td class="numericalColumn"> "           16.83" </td>}

# printout raw value
> puts cell.to_plain_text
16.83
=> nil

Regards.
