html parser / assertions in a model

rubyonrails-talk
1

I am using http.get in a model to parse html code returned from a Oracle server.

My first try was to use assertions (assert and assert_select) to test and parse the html code. But I have problems including the methods in the model. Have tried both "include" and copy/paste to get assertion methods into my model. Works as a model, but I get load errors when I am using the model from a controller.

Does anyone known the correct way to get assertion methods merged into a model?

I am considering replace assertions with a html parser. Is there a recommented html parser for ruby?

Ok, it looks like I have to use both load and include to prevent load error when the model with assertions are used from a controller.

load '/usr/lib/ruby/1.8/test/unit/assertions.rb' class OlapDatabaseTrans < ActiveRecord::Base   include Test::Unit::Assertions   ... end

That's, er, interesting :slight_smile:

I would think so -- take a look at http://github.com/tenderlove/nokogiri

Why do you need assertions to parse HTML? Assertions are for tests, not generic parsing.

What do the errors say?

Good idea.

I think most people are using Nokogiri these days.

Best,

Definitely Nokogiri, maybe with Mechanize...
