Subject: Re: html parser with regex, how to solve?

Don't use the regex. Let hpricot do what it's good at:

$ irb
 >> require 'rubygems'
 >> require 'hpricot'
 >> html = '<h3 class="zmp">149.00</h3>'
 >> doc = Hpricot.parse(html)
 >> ele = doc.search('h3.zmp')
 >> puts ele.text
=> 149.00

In your code, your @content will be searchable the same way. Hpricot  
will give you a collection of all h3's with class 'zmp'.

Hope this helps.
