Subject: Hpricot and xpath

Hi all,

I want to find the path to a tag I am interested using hpricot.
According to the document and examples I think I should use #xpath
method.

I expect that ruby will return the path as this:
"/tag1/tag2/div[@id='header']"

but I get the following info:

tag1.rb:4: undefined method `xpath' for nil:NilClass (NoMethodError)

I wonder why method #xpath is not defined?

Thanks,

Li

Here is my code:

require 'hpricot'
doc=Hpricot(open('tag.txt'))
puts doc
puts doc.at("header").xpath()


########tag.txt##########
<tag1>
     <tag2>
       <div id='header'>
     </tag2>
</tag1>
