hpricot results in an rhtml file

Hello,

I have the following code in an rhtml file as part of a rails app:
<html>
<head>
	<title></title>
</head>
<body>
	<h1></h1>
</body>
<p>It is now <%= Time.now %></p>
<p>

<%
require ''rubygems''
require ''hpricot''
require ''open-uri''

doc = Hpricot(open("http://www.mass.gov/legis/184history/h00024.htm"))

puts doc
%>
</p>
</html>

Hpricot is doing it''s job and grabbing the mass.gov code, I can see it
happening in the console.  However, I can''t get the mass.gov code to
display on the rhtml page.

Is this even possible?  What am I missing?''

Thanks,
John

It''s certainly possible, it''s just that puts doesn''t
do what you think it
does. Also, most of that code should be in the helper, or possibly even in
the controller. Consider this:


### helper file

require ''hpricot''
require ''open-uri''

module FooHelper
  def processed_mass_gov_data
    doc =
Hpricot(open("http://www.mass.gov/legis/184history/h00024.htm"))
    # I assume you have reason to use Hpricot rather than just putting the
    # retrieved HTML directly in the file, so this is where you''d do it
    doc.to_html
  end
end

### view

<html>
<head>
	<title></title>
</head>
<body>
	<h1></h1>
</body>
<p>It is now <%= Time.now %></p>
<p>
<%= processed_mass_gov_data %>
</p>
</html>
> Thanks,
> John--Greg

use <%= instead of <% or nothing will be added to the page (the result
of the block of code (if any) will be discarded).

here replace "puts doc" with "doc". puts ouputs on the
standard output,
not the page. If you replace it with "doc" only, it will be the result
of the code block which is what you want.> %>

Re: hpricot results in an rhtml file

If I did just want to place the retrieved HTML directly, how would I do
that?

Thanks for the help, obviously new to ROR.

Re: hpricot results in an rhtml file

I assume you''re going to process and massage that retrieved HTML,
right?
''Cause as soon as the browser sees the retrieved </body> tag, I
can''t
imagine there wouldn''t be potential problems with the rest of your app
[after the puts doc] showing up. And I''ll probably have nightmares
about
traversing the FrankenDOM!

Re: hpricot results in an rhtml file

Greg,

With this method, can I strip out certain tags, or have it just call
certain tags?

Thanks.

You can do all sorts of magic with Hpricot. Just using open().read to splat
it on the page won''t do that, however.

It looks to me like you need to sit down with irb and figure out what steps
you need to take to convert what you get from the original URL to what you
actually want. Once you''ve gotten that code working dependably you can
call
it from the controller and put it in an instance variable, which you can
refer to in the view.

I may be mistaken, but it looks to me like you are trying to use Rails
without actually learning Ruby. This is a mistake, and will not serve you
well. I recommend David Black''s excellent book "Ruby for
Rails" in this
case, in addition to the pickaxe book.
