How can one get the Hpricot DOM document from Mechanize?

Randy R

I was wondering if there were some way of getting the Hpricot DOM (for
lack of a better term) from a Mechanize page. For example:


agent = WWW:Mechanize.new
page = agent.get(http://www.w...)

# I am currently doing this
doc = Hpricot(page.body)

# I would like to do this
doc = page.get_hpricot_dom


The idea is that since Mechanize apparently uses Hpricot and it's surely
using it to parse the HTML begotten from the agent.get method, it would be
nice if I didn't have to repeat that work.
Is there a way to get this Hpricot document? ...or am I just totally
wrong about how Mechanize uses Hpricot?
Thank you...

Try page.parser or page.root (they're eqivalent).

You can get at the Hpricot document by using the "parser" accessor on
WWW::Mechanize::Page. Page also responds to "search", "/", and "at",
which just delegate to the Hpricot document.

So you can just do:

(agent.get('http://tenderlovemakin...)/'tr').each do |tr|
...
end
